Definitions

  • the present invention relates to a system and a device for carrying out measurements and / or interventions in a well drilled or being drilled by means of an electrical connection connecting the surface to a probe comprising means for measuring and / or d 'intervention.
  • the electrical connection comprises a section of cable cooperating at its lower end with measurement and / or intervention means and comprising at its other upper end a first intermediate connector secured to a support, a second intermediate connector adapted to cooperate electrically with the first intermediate connector and attached to a cable connected to the surface.
  • Patent FR-2501777 discloses a method and a device for carrying out measurements and / or interventions from a probe fixed to the end of a rod train, but this document only relates to logging devices. and has no intermediate connectors. Rotation of the entire packing in the well is not possible when the probe is connected because of the presence inside the drill string of the coaxial or annular cable when using a fitting with side window.
  • the present invention makes it possible to connect measuring and / or intervention means and in particular to allow the rotation of the whole of the lining and the addition of rods without having the need to bring the means up to the surface with all of the coaxial cable thanks to intermediate connectors and a suitable support.
  • Document GB-1557863 discloses a method and a device for transmitting information coming from a probe lowered into a drill string, said probe being suspended from a section of cable, said section being connected to the surface by means of 'a connector and a cable.
  • the probe is lowered to the cable in the packing and must therefore have an outside diameter compatible with the inside passage of the tubular packing. The installation of the section suspension device takes place on the surface.
  • the present invention allows the descent into a drill string of a probe comprising measuring and / or intervention means, said probe being fixed to the end of a section of cable which comprises a support for a first connector intermediate.
  • the connection is made by a second intermediate connector fixed to the end of a cable connected with the surface.
  • the support is secured to the rod train by remote control from the surface. It then suffices to raise the length of the cable above the second intermediate connector, which only causes a very short time loss and allows high capacity transmissions thanks to the cable.
  • this invention is economically very advantageous for the phase of controlling the trajectory of the borehole in the curvature and in the substantially horizontal part.
  • the tools used in the prior art are in particular transmission by pressure waves in the fluid in order to be able to rotate the entire lining without being hindered by a cable or not having to wind up the entire cable.
  • the length of the section can correspond to the start dimension of the deviation or Kick-off-point, and as the length of drilling in short radius is limited to a few hundred meters, the maneuvers of the cable connected to the surface are simple and fast during the whole deviation phase.
  • the frequency of measurements and interventions with the invention is thus comparable to that which can be obtained with transmissions without electric cable and moreover with less cost and less complexity.
  • rotation of the entire packing is allowed when the cable is brought to the surface.
  • the invention will be advantageously applied because it provides mechanical support to take up the weight of the cable and the tension forces generated on the cable in particular by an energetic circulation of a fluid refrigerant. Indeed, in very deep boreholes, the tension that a continuous cable would bear is greater than the tension authorized.
  • the solution is therefore to have intermediate supports of sections of acceptable length.
  • the connector may include means for locking said probe (25).
  • the support secured to any zone of the inner channel of the drill string can keep said section substantially taut.
  • the support may have cable recovery means at its upper end.
  • the drill string may include a special connector provided with a side opening through which said cable is placed.
  • the connector may include a system for angular orientation of said probe.
  • the assembly may include directional drilling means and means for controlling the position of said drilling means from the surface.
  • the assembly may include other measurement and / or intervention means electrically connected to a first connector integral with said assembly and in that said probe comprises a second connector adapted to connect with the first.
  • At least one of the second intermediate connector or of the probe may include a ballast such as load bars and / or a pumping device in the channel of the drill string.
  • the support may include a shaft secured on one side to said first electrical connector and on the other to a section of cable comprising electrical conductors, a body coaxial with said shaft, said body being able to move in translation between two extreme positions relative to said shaft, in a first position the support can be anchored, in the second position the support can be free to be moved and a locking system can secure said body to said shaft in the second position.
  • the locking system can be remote controlled electrically and can be reversible.
  • the body may include friction pads.
  • the support can include inoperative anchoring corners when said body is in second position, said corners can be adapted to anchor the support in the interior space of the drill string by the cooperation of expansion means when said body is in first position and when the expansion means are integral with the shaft, the corners may be integral with the body or vice versa.
  • the system according to the invention can be used for recording measurements and / or for occasional interventions in an oil well, while having the possibility of making rod additions and / or turning the entire drill string and said set between each measurement and / or intervention.
  • the present invention relates to the configuration of FIG. 5.
  • FIG. 5 represents a well 1 in which there is a drill string 2 at the end of which is assembled an assembly 3 comprising a connector 26.
  • the connector 26 includes a guide and a centering of the probe so that it can function properly .
  • This connection can also include a conventional mechanical anchoring, for example that described in the patent FR-2501777 already cited and possibly a system for angular orientation of said Mule-shoe type probe.
  • the assembly 3 does not include measurement and / or intervention means.
  • a probe 25 comprising measuring and / or intervention means is mechanically fixed to the lower end of a section of cable 6 comprising electrical conductors.
  • the upper end of this section has a first intermediate connector 8 secured to a support 7 which secures this first intermediate connector in the inner channel of the drill string.

  • a circulation head equipped with the conduit 14 makes it possible to pump the drilling fluid into the interior channel of the drill string, to supply the downhole motor to actuate the drilling tool and to clean the ring finger of the drilling debris.
  • the circulation head has an annular seal 13 adapted to the cable 10. This head is well known in the prior art.
  • the probe comprising measurement and intervention means are electrically connected to the surface by the section of cable 6, the two intermediate connectors and the cable 10. It is then possible to operate practically over the length of rods located above the drilling floor.

  • FIG. 2A illustrates this connection which is made using the same techniques as for connectors 4 and 5. Whenever it is necessary to execute an operation made impossible given the presence of the coaxial cable 10, it will suffice first to undock the second intermediate connector 9, to raise the cable 10 to the surface and then to operate. It is thus possible in particular to add rods in a conventional manner to deepen the borehole, to rotate the whole of the lining from a surface rotation means such as a rotation table or a motorized injection head.
  • a surface rotation means such as a rotation table or a motorized injection head.

  • the first intermediate connector 8 is integral with the liner 19. A traction applied to the liner and higher to the shear strength of the screw 21, releases the jacket upwards allowing the jacket, the first intermediate connector and the section 6 to rise.
  • the shirt 19 can also be fitted with fingers locking device remotely controlled from the surface as locking means 21.
  • the second intermediate connector 9 connected to the first is locked by means of fingers 22 secured to the jacket, the Said fingers cooperating with a retaining part 23 secured to the second intermediate connector. This retaining piece 23 can release the second connector when it is broken or be erasable by remote control from the surface of a motorization located above the intermediate connector 9.

  • Conductors 31 electrically connect the conductors of the cable section 6 to the intermediate connector 8.
  • Around the 'shaft 33 is disposed a body 34 comprising friction pads 35 and anchoring corners 36. This body is in lower support on a shoulder 37 secured to the shaft 33.
  • the body 34 is locked in the support position on the shoulder 37 by the cooperation of a finger 39 of a locking system 38 secured to the shaft and a hole 43 of the body 34.

  • Springs (not shown) keep the corners closed around the shaft.
  • An expansion means 41 of the anchoring corners is integral with the shaft.
  • the friction pads 35 are pushed radially by springs 42. These springs 42 provide the necessary contact force between the pipe and the pads to have sufficient longitudinal friction, in addition, they allow the pads to retract as the sections of reduced diameter at the tubular connections.
  • the support 7 of the section 6 is connected to the surface by the cable 10 fitted at its lower end with the second intermediate connector 9.
  • the locking of this connector 9 is effected by the cooperation of the fingers 22 and of a retaining piece 23 secured to the second connector 9.
  • the locking system 38 is electrically controlled from the surface by means of the cable 10 connected to the shaft by the two connectors. It is advantageous that this lock is reversible, that is to say that one can unlock or lock by remote control in particular from the cable 10. Such a lock is known and can be achieved in particular using 'A motor acting on the fingers 39. But in this invention, we can in some cases be satisfied with an unlocking system by breaking the fingers 39, in particular by explosive. In another embodiment, the corners may be integral with the shaft, while the expansion means is integral with the body.
  • FIG. 4B shows said support in its state anchored in the pipe 2.
  • the lock system 38 was ordered to be unlocked then by means of the cable 10 the shaft is allowed to slide by a distance H.
  • the relative sliding between the body and the shaft is obtained by means of the friction pads which keep the body 34 relatively stationary relative to the pipe and by the action of a downward displacement force of the shaft.
  • This force can be provided in particular by the weight of the shaft, the weight of ballast secured to the second connector 9, the weight of the section 6 and / or the tension applied to the section 6 when its end is anchored in the assembly 3.
  • the support 7 according to the embodiment of FIG. 4A can be anchored without the preponderant action of the gravity. It is enough to tension the section to lengthen it by a length greater than H, then unlock the body of the shaft before releasing the tension to bring the support 7 into the state shown in FIG. 4B.
  • the relative displacement of the length H between the shaft and the body causes the expansion means 41 and the anchoring corners to cooperate.
  • the conical shape of the expansion means pivots the corners around the axes 40 until these are applied to the wall of the pipe.
  • the displacement force as described above maintains the anchoring of the support 7 in the pipeline.
  • the external shape and the angle of pivoting of the corners allow the anchoring of the support on sections of the pipe of different diameters.
  • the tubulars used, drill rods, casing, tubing, etc. often have variations in internal diameter, particularly at the fittings.
  • the present support can be anchored at any level in a pipe having variations in internal diameter.
  • the separation or disengagement of the support is done by lowering again the cable 10 and its connector 9 equipped with a part 23 of resistance to rupture greater than the anchoring force. This resistance must also be greater than the force necessary to disengage the section 6 of the assembly 3, in the case where it is not not remote controlled. If the retaining part can be erased by remote control, this operation of the cable 10 will be avoided.
  • the supports according to the embodiments of FIG. 3 and 4A include electronic means which can be raised with the said supports in particular to amplify or help the transmission of information between the probe 25 or the assembly 3 and the surface.
  • These electronic means can be located at the upper end of said section 6 or at the lower end of cable 10.
  • the support 7 is possibly adapted to be able to keep section 6 substantially taut, the connection of connectors 4 and 5 being locked in particular according to the same principle described in FIG. 3 for connectors 8 and 9 .
