Definitions

  • ABSTRACT There is disclosed a method and apparatus for cementing a tubular string in a well bore wherein the tubular string is simultaneously rotated and reciprocated while passing a cementing slurry into the well bore.
  • cement aids chiefly in agitating the cement. and 'assuring a generally uniformplacement thereof in the-annulus. It is accordingly widely practiced to rotate orrreciprocate a tubular string while .pumping acement slurry into the well bore.
  • the casing string is neously rotating and reciprocating a tubular string in a well bore while passing a cementing slurry into the well bore.
  • There are two approaches'for simultaneously rotating and reciprocating a tubular string which have been the subject of conversation. Applicant is unable to state whether these approaches have ever been published or publicly used to bring these approaches within the purview of the prior art. It will suffice for present purposes to state that applicantis not the inventor of the approaches hereinafter described.
  • One approach is to run the tubular string through the rotary table into the well bore, set the casing slips on the string, attach a sub to the female coupling at the top of the tubular string, attach'theKelly to the sub, remove the casing slipsandrotary bushing, lower the string such that the Kelly. extends through the rotary table, place the Kelly bushing in the rotary table and then simultaneously rotate and reciprocate the tubular string.
  • 1' his approach presents two primary disadvantages, either of which is so severe as to preclude serious consideration of this approach for use in a cementing process.
  • the "first disadvantage occurs if the casing string becomes stuck in the well bore. In this event, the 'Kelly must'be'removed from the casing string in order to attach suitable fishing tools, for example.
  • blowout preventer could presumably be cut off with an acetylene torch and a makeshift table fabricated to receive casing slips and thereby suspend the casing in order to break 7 the joint between the sub and the tubular string. It will curring tremendous expense. Since the odds of this happening are small, it will be readily apparent that no serious consideration is given to simultaneously rotating and reciprocating a tubular string while cementing by using the Kelly.
  • the second approach discussed in conversation but which is not known to applicant'to be within the purview of the prior art, is to rotate the casing string with a set of power casing tongs while reciprocating the casing string with the drawworks.
  • the casing is run into the well bore, the casing slips are set in the rotary table, the casing tongs are attached to that part of the casing string extending above the rotary table, a cementing head is attached to the tubular string, the elevators are attached to the casing string, the casing tongs are tied off against a leg of the derrick the easing slips are removed from the rotary table, and the easing string is rotated with the casing tongs while the string is reciprocated with the drawworks.
  • This ap proach avoids sticking the casing or setting up the cement and not being able to attach suitable fishing tools to the casing string.
  • One prime disadvantage of this approach is that the casing string can be reciprocated through a stroke of less than about three feet since the tie-off to the derrick leg allows only very limited reciprocating travel.
  • Another prime disadvantage of this approach is that power casing tongs presently available are incapable of applying substantial torque to the casing string at substantial rotational speeds. In other words, this approach does not allow the tubular string to be rotated fast enough nor reciprocated through av sufficient stroke to scratch the bore hole wall to any extent. Thus, this approach is less satisfactory than either solely reciprocating the tubular string with the drawworks or solely rotating the string with the rotary table. Accordingly, no serious consideration has been given this approach for cementing a tubular string in a well bore.
  • Another object of this invention is to provide a cementing technique and apparatus for simultaneously rotating and reciprocating a tubular string while maintaining the rotating tool above the derrick floor and passing a cementing slurry into the well bore.
  • the cementing method of this invention comprises rotating a tubular string; reciprocating the string up and down for a stroke of at least feet while rotating the string and maintaining the tool above the floor; and passing a cementing slurry into the well bore during rotation and reciprocation of the string.
  • the apparatus of this invention comprises swivel means having a stationary portion including a fluid inlet and means for attaching the swivel means to hoist means for raising and lowering the apparatus, and a rotatable portion including a fluid outlet in communication with the fluid inlet; a power sub having a conduit and means for rotating the conduit; and a cementing sub comprising a conduit and means for launching at least one cementing plug into the tubular string, the power sub conduit and the cementing sub conduit being in torque transmitting relation and in fluid transmitting relation between the swivel fluid outlet and the tubular string.
  • FIG. 1 there is illustrated a drilling rig 10 comprising a floor 12 elevated above a ground surface 14 by a structure 16.
  • the drilling rig 10 includes a rotary table 18, a derrick (not shown), a drawworks (not shown) and other typical equipment.
  • a bore hole 20 is illustrated as extending into the earth and penetrating a formation 22.
  • a tubular string 24 is illustrated as extending into the bore hole 20 and is comprised of a plurality of joints of pipe of any desired size.
  • the tubular string 24 carries a plurality of scratchers 26, a cementing shoe 28 and such other cementing equipment, for example centralizers, float equipment and the like, as may be desired during the cementing of the string 24 in the bore hole 20.
  • equipment 30 comprising as major components a swivel unit 32, a rotating tool 34 and a cementing sub 36.
  • the swivel unit 32 is illustrated as suspended from elevators 38 which areconnected by bails 40 to the traveling block (not shown) and drawworks (not shown) which are customarily part of the drilling rig 10;
  • the equipment 30 accomplishes simultaneous rotation and reciprocation of the string 24 by energizing the rotating tool 34 simultaneously with raising and lowering of the elevators 38.
  • the swivel unit 32 is illustrated in greater detail.
  • the swivel unit may be any desired type and is illustrated as a fishing tool swivel manufactured by Texas Iron Works of Houston, Texas.
  • the swivel unit 32 comprises a stationary portion 42 and a rotatable portion 44.
  • the stationary portion 42 is illustrated as comprising a solid shank 46 having a shoulder 48 thereon received in the elevators 38.
  • the shank 48 is conveniently threaded into the top of a sleeve 50 which also comprises part of the stationary portion 42.
  • the sleeve 50 includes a fluid inlet 52, a fluid passage 54 for transmitting liquids or slurries pumped into the well bore 20 during the course of operation.
  • the rotatable portion 24 is conveniently made in two parts 56, 58 which are threaded together.
  • Suitable bearings 60 mount the portion 44 for rotation about the centerline of the swivel 32.
  • Suitable seals 62, 64 and grease fittings 66, 68 may be provided as desired as will be recognized by those skilled in the art.
  • the part 58 comprises a fluid outlet 70 in communication with the fluid inlet 52 and also provides a threaded connection 72 for securement to the rotating tool 34.
  • the rotating tool 34 may be of any desired type so long as it has operating characteristics commensurate with its desired functions. As will be more fully apparent hereinafter, the rotating tool 34 transmits liquids or slurries pumped into the swivel unit 32 to the cementing sub 36, allows reciprocation of the equipment 30 through a stroke of at least feet and rotates the string 26 at desired torque and speed levels.
  • the desired torque level is, of course, less than the collapse strength of the screw couplings which connect the joints of the string 24 together.
  • the rotating tool 34 comprised a power sub manufactured by Bowen Tools, Inc., Houston, Texas. This particular device is described in an instruction manual printed December, 1965. As reported on page 23 of this manual, the maximum torque of such devices is 6,000 foot pounds.
  • the rotating tool 34 is illustrated as comprising a conduit 74 attached at the upper end thereof to the threaded connection 72 and at the lower end therof to the cementing sub 36.
  • a housing 76 encloses a gear wheel operatively connected to the conduit 74 and driven by a hydraulic motor 78.
  • the housing 76 includes a bracket 80 apertured to receive astationary guide 82 therethrough. It will be seen that the rotating tool 34 is constrained for vertical movement by the guide 82 which actsto ensure that the conduit 74 is rotated rather than the housing 76.
  • the motor 78 is provided with suitable hydrauliclines 84, 86 for delivering and returning power fluid from the motor 78 to a suitable pump (not shown). Suitable controls and pressure gauges are provided as desired. As will be apparent to those skilled in the art, pressure readings from the lines 84, 86 may be used to determine the torque and speed delivered by the motor- 78.
  • the cementing sub 36 may be of any suitable type and is illustrated in F IG. 3 as comprising a coupling 88 connected to the conduit 74, a bypass manifold 90, a conduit 92 connected to the coupling 88 at one end thereof and to a coupling 94 at the other end thereof.
  • Suitable valves 96, 98, 100 are provided to deliver fluid from the manifold 90 to selected locations along the conduit 92.
  • Cement plug gates 102, 104 are provided for delivering at least one and preferably at least two cementing plugs into the string 24.
  • a clean drilling mud slurry is initially circulated through the well bore by closing the valves 98, 100 and opening the valve 96. It will be seen that the clean drilling mud passes through the cementing sub 36 without disturbing the cement plugs 106, 108 respectively positioned above the gates 102, 104.
  • cement is pumped into the fluid inlet 52 while the valve 96 is closed, the valve 98 is opened and the cement plug gate 102 is open. It will be seen that cement passes through the swivel unit 32, the bypass manifold 90, the valve 98 and the conduit 92 to force the cement plug 106 from its resting position above the gate 102 into the tubular string 24.
  • drilling mud is again pumped into the fluid inlet 52, the valve 98 is closed, the valve 100 is opened and the cement plug gate 104 is opened. It will be seen that drilling mud will pass through the swivelunit 32, the bypass manifold90, the valve 100 and the conduit 92 to force the cementing plug 108 downwardly into the tubular string 24. As the cementing plug 108 reaches the cement shoe 28, the fluid passage therethrough is closed and no further liquid can be injected into the well bore 20.
  • the swivel unit 32 provides an attachment to the hoist means of the drilling rig 10, provides for the injection of drilling mud and cement slurry into the well bore 20 and allows rotation of the components suspended therefrom.
  • the rotating tool 34 causes rotation of the string 24 and does not interfere with reciprocation of the string 24 throughout a stroke of substantial length.
  • the cementing sub 36 provides for the launching of one or more cementing plugs.
  • the tubular string 24 is run through the rotary table 18 into the well bore 20 in a conventional manner.
  • the cementing sub 36 is attached thereto.
  • the rotating tool 34 is then threaded into the top of the cementing sub 36 and the threaded connection between the swivel 32 and' the rotating tool 34 is made up.
  • the guide 82 is operatively connected to the bracket and a suitable flexible hose is connected to the fluid inlet 52.
  • the mechanism 30 is accordingly ready to commence simultaneous rotation and reciprocation of the string 24.
  • the driller manipulates the drawworks in a conventional manner to raise the elevators 38 and thereby raise the string 24.
  • Power hydraulic fluid is delivered through the line 84 to drive the motor 78 and thereby rotate the string 24.
  • Reciprocation of the string 24 for a stroke less than about 10 feet' is not contemplated. Accordingly, the driller continues to raise the elevators 38 until the desired stroke is achieved.
  • the weight of the string 24 causes the string 24 and the equipment 30 to fall into the well bore 20.
  • the rate of descent of the equipment 30 is controlled by the drawworks brake in a conventional manner.
  • Rotating and reciprocating the string 24 in this fashion causes the scratchers 26 to abrade the wall of the bore hole 20 and thereby remove cuttings embedded in the bore hole wall, excess filter cake and the like.
  • clean drilling fluid is pumped into the inlet 52, down the string 24, through the cementing shoe 28 and upwardly through the annulus and is returned to the mudpits in a conventional manner.
  • Rotating and reciprocation of the string 24 is temporarily halted in order to close the valve 96, open the valve 98 and open the cement plug gate 102.
  • the cementing trucks then connect to the flexible hose attached to the fluid inlet 52 and commence pumping a cementing slurry into the equipment 30. contemporaneously with the delivery of cementing slurry into the string 24, rotation and reciprocation of the string 24 is commenced.
  • valve 98 When sufficient cementing slurry has been introduced into the string 24, rotation and reciprocation of the equipment 30 is temporarily halted, the valve 98 is closed, the valve is opened, the cementing plug gate 104 is opened and connections are made to pump drilling mud into the fluid inlet 92. Rotation and reciprocation of the string 24 is again commenced and drilling mud is pumped into the inlet 52.
  • Rotating and reciprocating the casing string 24 after the second cementing plug 108 is down causes kneading or working of the cement in the annulus to ensure that the cement completely fills the annulus from the bottom of the well bore 20 to a predetermined level above the formation 22.
  • the well bore 20 may have washouts or enlargements that need to be completely filled with cement.
  • Rotation of the string 24 aids in complete dispersion of the cement since the scratchers 26 and the centralizers (not shown) act to some extent as paddles. Simultaneous reciprocation of the string 24 acts to some extent-as a plunger to propel cementing slurry laterally into washouts and the like.
  • the elevators 38 may be lowered so that at least a substantial part of the weight of the string 24 is borne by the cementing shoe 28 and by frictional engagement of the string 24 with the bore hole wall. This condition is illustrated in FIG. 4 where the string 24 is offset with respect to the bore hole centerline 110. Since the casing string 24 is offset, rotation thereof churns the cement in the annulus to a substantially greater extent than the conventional approach.
  • a method of cementing a tubular string comprised of a plurality of threadably connected joints having thereon means for frictionally engaging a bore hole wall, in a well bore from the floor of a rig with a tool including a hydraulic torque applier and means for controlling the applier for varying the torque output of the tool, the method comprising the steps of rotating the tubular string with the tool;
  • a method of cementing a tubular string comprised of a plurality of threadably connected joints having thereon means for frictionally engaging a bore hole wall, in a well bore from the floor of a drilling rig spaced above an underlying surface, the method comprising the steps of running the tubular string through a table on the rig into the well bore;
  • a method of cementing a tubular string in a larger bore hole comprising the steps of delivering cementing slurry into a bottom part of the annulus between the string and the well bore; placing the string in compression; and
  • the method of claim 5 further comprising the step of installing a swivel in the tubular string adjacent the lower end thereof and wherein the placing step comprises the steps of suspending the string in a well bore with hoist means; manipulating the hoist means to place the lower string end on the bottom of the well bore; and
  • a method of cementing a tubular string comprised of a plurality of threadably connected joints having thereon means for frictionally engaging a bore hole wall, in a well bore from the floor of a rig with a tool including a torque applier and means for controlling the torque applier for varying the torque output of the tool, the method comprising the steps of running the tubular string into the well bore;
