Definitions

  • This invention relates to new and improved apparatus for reliably and quickly interconnecting electrical devices and electronic circuitry in a multi-section well tool when, for example, the tool is being assembled on a drilling rig. More particularly, the present invention relates to new and improved apparatus for interconnecting electrical means respectively enclosed in separable thick-walled tubular bodies which are tandemly coupled together by their respective threaded end portions.
  • Mating electrical connector means connected to the electrical means in each tool body are cooperatively arranged to be selectively positioned within the tool bodies so that when the bodies are being threadedly coupled together, the mating connector means will be reliably interconnected without the male end portion of one tool body damaging the connector means as it is inserted into the female end portion of the other tool body and rotated to bring the bodies into coincidental alignment as their end portions are threadedly coupled together.
  • these measurements include such data as the weight imposed on the drill bit, the torque applied te the drill string, the inclination and azimuthal direction of the borehole interval that is then being drilled, borehole pressures and temperatures, drilling mud conditions as well as various characteristics of the earth formations being penetrated.
  • most of these measurements were obtained either by temporarily positioning special measuring devices in the drill string or by periodically removing the drill string and employing suitable wireline logging tools.
  • the drilling technology has advanced sufficiently that these measurements can now be readily obtained by so-called measuring-while-drilling or "MWD” tools that are tandemly coupled in the drill string and operated during the drilling operation.
  • MWD tools that are tandemly coupled in the drill string and operated during the drilling operation.
  • the MWD tools presently in commercial operation typically include a thick-walled tubular body carrying various sensors and their associated measurement-encoding circuitry which is preferably positioned in the drill string just above the drill bit for measuring the condtions at the bottom of the borehole.
  • These commercial tools generally employ a selectively-operable acoustic signaler which is cooperatively arranged in the upper end of the tool body for successively transmitting encoded measurement signals through the drilling mud within the drill string to the surface where the signals are detected and recorded by suitable surface instrumentation.
  • the ideal MWD tool should be arranged as a multi-sectional tool having various special-purpose cartridges that are respectively housed in separable thick-walled bodies and suitably arranged to be coupled together in various combinations for assembling a MWD tool capable of obtaining one or more selected measurements.
  • One obvious advantage of such a multi-sectional tool is that a tool section which either is not needed for a particular operation or is malfunctioning can be quickly removed without disturbing the other sections of the tool.
  • the tool should be easily and quickly assembled and disassembled by using the rig tongs while the tool is supported in the slips on the rotary table of the drilling rig.
  • the separable tool bodies utilize threaded end portions with tapered threads such as those customarily used for drill collars or joints of drill pipe.
  • the tool body must be reconditioned either by cutting off the damaged threads and rethreading the damaged end portion or by replacing the entire threaded end portion.
  • its overall length will be changed; and, before that body can be reused, some modification must be made to the connector means or to any cartridge that is to be subsequently placed in that body before other tool bodies can be utilized with the reconditioned body.
  • head assemblies that are cooperatively arranged to be respectively mounted at the opposite ends of the axial bore of an elongated tool body.
  • These head assemblies respectively include first electrical connector means having outwardly-directed contact members coaxially mounted in the tool body. At least one of the first electrical connector means in each tool body is cooperatively arranged for being initially positioned at a selected location on the longitudinal axis of the tool body so that as the body is being threadedly coupled to other similarly threaded bodies, their respective contact members will be safely brought into mating engagement with one another.
  • the head assemblies of the present invention further include inwardly-directed socket means respectively arranged for cooperatively supporting and fluidly sealing a tubular housing carrying electrical means.
  • the head assemblies further include second connector means cooperatively arranged for releasably interconnecting the first connector means with the electrical means supported within the tool body.
  • FIGURE 1 a new and improved tool section or so-called “instrumentation sub” 10 arranged in accordance with the principles of the present invention is depicted as it will appear before it is coupled to a similar sub for assembling a MWD tool equipped for obtaining one or more selected downhole measurements.
  • instrumentation subs as at 10 having the necessary instrumentation and measurement circuitry are coupled to other subs (not shown in the drawings) carrying a mud-driven generator fpr powering the tool and an acoustic signaling device.
  • the assembled MWD tool is tandemly coupled in a drill string just above the drill bit and operated during the course of a drilling operation for successively measuring the downhole conditions and transmitting those measurements to the surface.
  • the instrumentation sub 10 is basically comprised of an elongated, thick-walled tubular body 11 having its upper and lower end portions respectively provided with female and male threads 12 and 13 which are preferably the same as used for conventional drill collars of the same external diameter.
  • a fluid-tight tubular housing or cartridge 14 is coaxially mounted within the tool body 11 and arranged to enclose electrical means such as various electrical devices or electronic circuitry 15 to obtain measurements or perform given functions related to the overall operation of the MWD tool.
  • the cartridge 14 is made significantly shorter than the thick-walled tubular body 11 and is centrally positioned therein for providing substantial clearance spaces in the upper and lower portions of its axial bore 16 in which new and improved upper and lower head assemblies 17 and 18 are mounted.
  • these head assemblies 17 and 18 respectively include central support members or bodies 19 and 20 which sealingly receive the upper and lower ends of the cartridge 14 and coaxially position the cartridge within the tool body 11.
  • the head assemblies 17 and 18 also include electrical connector means 21 and 22 cooperatively arranged on the bodies 19 and 20 for releasably interconnecting the electrical means 15 in the cartridge 14 with electrical means in other tool subs that may be coupled to the sub 10 to assemble a given multi-sectional MWD tool.
  • the lower portion of its axial bore 16 is reduced in diameter to define an upwardly-facing shoulder 23 on which the central body 20 of the lower head assembly 18 is rested and secured by means such as one or more bolts 24 in the lower portion of the thick-walled body.
  • one or more centralizing members, as at 25, may also be mounted on intermediate portions of the cartridge 14 to prevent its unwanted lateral movement within the tool body 11.
  • bypass passages 26 are appropriately arranged in the centralizing member 25 and, as shown at 27 and 28 in FIGURES 3 and 4, in the central bodies 19 and 20 respectively.
  • FIGURE 2 the adjacent end portions of two tool subs 10A and 10B which are respectively arranged in accordance with the principles of the present invention are depicted as they will appear when they are tandemly coupled together to assemble a MWD tool requiring the electrical means in the cartridges 14A and 14B.
  • the upwardly facing shoulder 23A serves to position the lower head assembly 18A well above the lower end of the tool body 11A.
  • the electrical connection means 22A of the lower head assembly 18A include a downwardly-facing electrical connector 29A that is coaxially positioned within the axial bore 16A just above the lower end of the tool body 11A by an elongated support member 30A that is dependently coupled to the central body 20A.
  • the electrical connection means 21B of the upper head assembly 17B include an upwardly-facing electrical connector 31B adapted for mating engagement with the connector 29A.
  • the connector 31B is coaxially aligned within the axial bore 16B and positioned just below the upper end of the tool body 11B by an upright tubular support member 32B coaxially mounted on the upper end of the central body 19B.
  • the mating electrical connectors 29A and 31B are cooperatively arranged to interconnect the electrical means respectively enclosed within the two cartridges 14A and 14B.
  • FIGURE 3 a partially cross-sectioned, elevational view is shown of the upper and lower portions of the upper head assembly 17 in the upper end of the tool body 11.
  • the upper end of the cartridge 14 is threadedly engaged within a downwardly-facing threaded socket 33 coaxially arranged in the lower end of the central body 19 and fluidly sealed therein by means such an 0-ring 34.
  • a closure member 35 fitted in the upper end of the cartridge 14 is terminated by a reduced-diameter end portion 36 with an axial bore 37 carrying an electrical connector 38 connected to one or more conductors from the electrical means 15 (not seen in FIGURE 3) enclosed in the cartridge.
  • the electrical connector 38 includes a body 39 with an upwardly-opening axial bore which is fitted within the axial bore 37 of the closure member 35 and secured by a tubular retainer 40 that is threadedly engaged over the upright end portion 36 of the closure member to press an external rib 41 around the connector body against the upper transverse surface of the end portion.
  • Sealing means such as 0-rings 42 and 43 respectively mounted around the connector body 39 and the retainer 40, are arranged for blocking the entrance of drilling mud into the socket 33 and the upper end of the cartridge 14.
  • the electrical connector 38 further includes at least two contact members which, in the illustrated preferred embodiment of the upper head assembly 17, are comprised of a small conductive sleeve 44 coaxially disposed in the rearward portion of an insulating sleeve 45 and a larger conductive ring 46 coaxially mounted in the forward end portion of the insulating sleeve.
  • the lower end of the upright support member 32 is fitted over the retainer member 40 and threadedly secured within an upwardly facing counterbore 47 in the upper end of the central body 19. Sealing means, such as an 0-ring 48 between the retainer 40 and the support member 32, prevent the entrance of drilling mud into the support member.
  • the upper portion of the tubular support member 32 is internally threaded as at 49.
  • the reduced-diameter lower end of a tubular connector body 50 is threadedly engaged within the threads 49 and adapted to be manually moved upwardly or downwardly as needed to correctly position the electrical connector 31 for subsequent mating engagement with another connector (such as the connector 29 in another tool sub) whenever the sub 10 is used to assemble a particular MWD tool.
  • the connector 31 further includes a protective sleeve 51 which is coaxially mounted around the mid-portion of the body 50 and the upper end of the support member 32. Sealing means such as 0-rings 52 and 53 are cooperatively arranged to prevent the entrance of drilling mud into the electrical connector 31.
  • a screw 54 secures the protective sleeve 51 to the connector body 50. Should it be needed to provide additional strength for the support 32 to better withstand axially directed impacts and thereby protect the threads 49, one or more annular spacers, as at 55, may be stacked in the space between the connector body 50 and the sleeve 51 and engaged between the upper surface of the support member 32 and the lower surface of the enlarged-diameter mid-portion of the connector body. The lengths and number of these spacers 55 will, of course, be dependent upon where the electrical connector 31 is to be positioned on the support 32.
  • the connector body 50 is counterbored to provide an enlarged-diameter axial bore 56 in the upper portion of the body and a reduced-diameter axial bore 57 in the lower portion of the connector body.
  • an elongated tubular member 58 having an enlarged-diameter upper portion and a reduced-diameter lower portion is slidably mounted in the upper and lower portions 56 and 57 of the axial bore of the connector body 50 for limited axial movement therein.
  • sealing means such as 0-rings 59 and 60 are cooperatively arranged between the connector body 50 and the slidable member 58.
  • An elongated slot 61 is provided in the connector body 50 between the 0-rings 59 and 60.
  • Biasing means such as a spring 62 in the axial bore 57, are provided for normally urging the slidable member 58 upwardly in relation to the connector body 50 and toward an elevated position as defined by stop means such as a set screw 63 one side of the slidable member that has its head slidably disposed within the slot 61.
  • the upper connector means 21 are arranged to quickly and reliably interconnect the electrical means in the cartridge 14 and the electrical means in another sub.
  • a multi-conductor cable 64 is disposed within the tubular extension member 32.
  • the cable 64 is provided with a typical male connector 65 on its upper end that is seated in an upright position within the slidable member 58 and a typical male connector 66 on its lower end cooperatively arranged to be progressively inserted into the female connector 38 as the lower end of the extension member 32 is being threaded into the threaded socket 47 on the central body 19.
  • the upper connector 65 is preferably secured to the slidable member 58 by an upright pin 67 and the lower connector 66 is secured to the extension member by a lateral pin 68.
  • the upper connector means 21 are cooperatively arranged to be removed by simply unthreading the extension member 32 from the socket 47 in the upper end of the central body 19.
  • the connector 31 can be selectively positioned on the extension member 32 by temporarily removing the set screw 54 and moving the protective sleeve 51 downwardly onto the extension member 32.
  • the connector body 50 must, of course, be temporarily removed if it is found necessary to remove or add spacer members as at 55. If the spacer members, as at 55, are not being used, it will be recognized that the connector body 50 can be readily moved upwardly or downwardly along the threads 49 without having to first remove the body from the extension member 32.
  • the sleeve 51 is resecured to the connector body with the screw 54.
  • FIGURE 4 the lower head assembly 18 of the present invention is seen as it will appear when mounted within the lower portion of the thick-walled sub body 11.
  • the lower end of the cartridge 14 is cooperatively received within an upwardly facing socket 69 coaxially arranged in the central body 20 and fluidly sealed and secured therein in a typical fashion.
  • a closure member 70 disposed within the lower end of the cartridge 14 is terminated with a reduced-diameter tubular end portion 71 carrying a multi-conductor cable 72 which is connected to the electrical means within the cartridge and terminated by a downwardly-facing electrical connector 73 which is preferably similar or identical to the female connector 38.
  • the upper end of the tubular support member 30 is coaxially disposed around the connector 73 and threadedly engaged within a downwardly facing socket 74 in the lower end of the central body 20.
  • Sealing means such as an 0-ring 75 between the central body 20 and the extension member 30 and an 0-ring 76 between the central body and a retainer 77 on the connector 73, are cooperatively arranged for blocking the entrance of drilling mud into the lower end of the cartridge 14.
  • the lower connector 29 is preferably similar to the connector 31 and includes a tubular body 78 that is threadedly coupled to internal threads 79 within the lower portion of the depending support member 30 and secured by a lock nut 80 once the connector body has been properly positioned.
  • a protective sleeve 81 is coaxially mounted around the connector body 78 and secured thereto as by a set screw 82. Sealing means, such as 0-rings 83 and 84, are cooperatively arranged between the connector body 78 and the sleeve 81 for sealingly enclosing the interior of the support member 30.
  • a tubular body 85 is threadedly coupled to the lower end of the connector body 78 and arranged to carry a small conductive sleeve 86 coaxially disposed in the upper portion of an insulating sleeve 87 and a larger conductive ring 88 coaxially mounted in the lower portion of the insulating sleeve. It will, of course, be recognized that these contacts 86 and 88 are sized and positioned within the insulating sleeve 87 to provide a female connector adapted to complementally receive a typical bayonet-type male connector (such as the connector 65) that is mounted in a companion tool sub that is being coupled to the instrumentation sub 10.
  • a typical bayonet-type male connector such as the connector 65
  • the closure members 35 and 70 are respectively mounted in the upper and lower ends of the cartridge 14 and the connectors 38 and 73 are secured in position by their respective retainers 40 and 77.
  • the upper and lower central bodies 19 and 20 are then fitted over the upper and lower ends of the cartridge 14 and this assembly is thereafter inserted into the axial bore 16 of the tool body 11.
  • the screws 24 are tightened to secure the lower central body 20 to the tool body. It will, of course, be recognized that removal of the cartridge 14 is carried out by simply reversing this assembly procedure.
  • the upper and lower electrical connector means 21 and 22 can be readily removed or installed.
  • the upright support member 30 is simply rotated as required to disengage it from the threaded socket 47. This, of course, removes the upper connector 31 along with the upper support member 30.
  • the connector body 50 can be manually rotated for moving the connector body upwardly or downwardly along the threads 49 so as to position the upper connector 31 in a desired location with respect to the upper end of the tool body 11.
  • the upper or forward end of the slidable member 58 will be spatially disposed a fixed distance below or to the rear of the transverse surface 89 on the upper female or box end of the tool body 11. Since this transverse end surface 89 must necessarily engage the opposing transverse surface or shoulder, as at 90 in FIGURE 4, just behind the male threads, as at 13, when the tool body 11 is tightly coupled to another tool body or sub, this longitudinal spacing will provide a standard measure for correctly positioning the connector 31 (as well as the connector 29).
  • the lower electrical connection means 22 are similarly arranged to facilitate the accurate positioning of the lower connector 29.
  • the lock nut 80 can be temporarily loosened to permit spatial adjustment of the connector body 78 along the internal threads 79.
  • the end of the tubular nose portion 85 must be positioned a fixed distance ahead of or below the transverse surface or external shoulder 90 of the tool body 11. It will be recognized that adjustment of the lower connector 29 is preferably carried out with the connecting means 21 mounted outside of the tool body 11.
  • the electrical connector means 21 and 22 permit the upper and lower connectors 31 and 32 to be adjustably positioned independently of one another as needed to accommodate changes in the overall length of the tool body 11 as might be necessary where the threads 12 or 13 have been reconditioned.
  • FIGURE 5 an enlarged view is shown of the bottom end of the body 11 to illustrate the interconnection of one of the lower connectors 29 with one of the mating upper connectors 31.
  • the connectors 29 and 31 must be correctly positioned in relation to their respective tool bodies 11. The extent of any preliminary adjustments will, of course, depend upon whether there has been a significant change in the relative positions of either of the connectors 29 or 31 with respect to its particular tool body 11. For instance, at times it will be necessary to remove the cartridge 14 and the upper and lower head assemblies 17 and 18 from a particular tool body 11 for repairing or replacing one of the threaded end portions as at 12 or 13. The change in the length of the tool body 11 resulting from such repairs or replacements will, of course, require that one or both of the connectors 29 and 31 be appropriately adjusted so that when the tool sub 10 is reassembled they will be properly positioned within the tool body.
  • the upper and lower connector means 21 and 22 are removed from the central bodies 19 and 20 by unthreading the support members 30 and 32 before the tool sub 10 is reassembled.
  • the cartridge 14 and the upper and lower head assemblies 17 and 18 are then installed in the body 11 and secured in place by the bolts 24.
  • the protective sleeve 81 is temporarily removed and the lock nut 80 is loosened so that the tubular member 78 may be appropriately raised or lowered along the threads 79 as needed for correctly positioning the nose of the connector body 85 in relation to the external shoulder 89 on the lower end of the tool body 11.
  • the overall length of the threads 79 provides substantial latitude for adjusting the tubular member 78 so that the connector 29 will be accurately positioned when the connector means 22 are subsequently replaced in the tool body.
  • the tubular support 30 could, of course, be easily replaced with a shorter or longer support member.
  • Measurements can be made to determine the longitudinal spacing between the lower end of the lower connector 29 and the shoulder 90 at the lower end of the tool body 11.
  • the support member 30 can, of course, be readily unthreaded from the lower central body 20 should it be necessary to adjust the position of the connector 29 in relation to the lower surface or shoulder 90 of the tool body 11.
  • the upper connector 31 is also correctly positioned on the extension member 32 before the upper connector means 21 are secured to the upper central body 19.
  • a stack of the annular spacers 55 of appropriate height is arranged on top of the extension member 32 and secured in place when the connector body 50 is adjusted on the threads 49.
  • the sleeve 51 is replaced and the extension member 32 is threaded into the socket 47 of the upper central body 19. It will be realized that the extension member 32 can also be readily removed from the central body 19 should the connector 29 require a minor readjustment to correctly position it in relation to the upper shoulder 89 of the tool body 11.
  • the above-described adjustments of the upper and lower connector means 21 and 22 can be easily carried out with only a minimum of skill needed to correctly position the connectors 29 and 31.
  • the pressure of time and the working conditions on a rig floor are often such that delicate adjustments or complicated equipment changes can not always be made.
  • the unique arrangement of the connector means 21 and 22 facilitate the replacement of sealing members and the correct positioning of the connectors 29 and 31 in a miniumum of time by even unskilled personnel.
  • the spring 62 will urge the body 58 upwardly until the screw 63 engages the upper surface of the slot 61. As shown in FIGURE 5, however, the spring 62 will be slightly compressed when one of the lower connectors 29 on another tool sub is inserted into the upper connector 31 so that the screw 63 will be disengaged from the upper surface of the slot 61. The biasing force of the spring 62 will, of course, tend to maintain the connectors 29 and 31 firmly engaged. Those skilled in the art will nevertheless recognize that the extreme shock forces that are continuously imposed on a MWD tool during a drilling operation could easily overcome this biasing force and thereby momentarily separate the connectors 29 and 31.
  • FIGURES 6A-6C successive views are shown of the end portions of two tool bodies 11 as the threaded male portion 13 of the upper tool body is being lowered into the threaded female portion 12 of the lower body to tandemly couple the two bodies.
  • the two connectors 29 ⁇ and 31 have been manually adjusted as respectively needed to correctly position them in the internal bores of the tool bodies. With the connectors 29 and 31 positioned as illustrated, they are, of course, well guarded from damage as the tool bodies are being separately handled prior to the illustrated coupling operation.
  • the lower connector 31 is sufficiently recessed in the upper end of the lower tool body 11 that the connector will not be struck by the male or pin end 13 of the other tool body as this threaded end portion is initially lowered into the box portion 12 of the lower tool body.
  • the upper tool body will be progressively moved into axial alignment with the lower tool body as the male threads 13 begin to coengage the female threads 12.
  • the connectors 29 and 31 will be brought together and cooperatively coupled together. It should be noted that even should there be a slight misalignment between the connectors 29 and 31, the spring 62 will compress sufficiently to allow the engagement of the threads 12 and 13 bring the tool bodies and the connectors into axial alignment without risking damage to the connectors.
  • the present invention has provided new and improved apparatus for reliably and quickly interconnecting the several sections of a multi-sectional well tool such as a MWD tool.
  • a multi-sectional well tool such as a MWD tool.
