Definitions

  • Flush joint (or 'near flush joint') pipe used for riser pipe in offshore drilling and/or used for conductor pipe for deep well drilling is often too large in diameter to be handled by conventional die-grip casing handling tools.
  • the most commonly available die-grip tools for handling large pipe have a maximum diameter capacity of approximately 61 cm (24 in).
  • Riser pipe and conductor pipe can have a substantially larger diameter, frequently in excess of 91 cm (36 in).
  • the present invention relates to special equipment and procedures for handling and running large diameter flush-joint pipe in offshore wells and/or other drilling sites requiring pipe having diameters exceeding the capacity of conventional running tools.
  • US 3063509 describes an elevator for assembling pipe joints.
  • the elevator is adapted to lift and position a first joint whilst it is stabbed and tightened onto a second joint.
  • US 4209066 and US 2719025 describe joint handling systems.
  • an elevator for assembling a plurality of a large diameter pipe joint into a pipe string with a drilling rig, a first one of the plurality of large diameter pipe joints being adapted to threadingly engage a second one of the plurality of large diameter pipe joints, the elevator being detachably securable to an upper end of the first joint, the elevator being adapted to both lift and position the first joint while it is stabbed and tightened onto the string, and characterised in that the elevator further includes formations adapted to co-operatively engage in recesses provided in a rotary table of the drilling rig to transmit rotary motion to the elevator and thereby rotatably tighten the second joint, to the first joint as the second joint is added to the string, the elevator comprising a bolt on collar adapted to be clamped to the first joint, the collar comprising a plurality of keystone-shaped recesses that extend over corresponding key-stone shaped projections attached to an external surface of the first pipe joint.
  • the elevator may have a plurality of lifting pad eyes for attachment to lift lines on the drilling rig, and one rotary table lugs may extend from the lifting pad eyes to engage the rotary table.
  • an elevator having two halves, each half comprising a plurality of bolt ears adapted to receive bolts for clamping the collar.
  • a large diameter pipe joint 11 is moved from a storage location on a drilling rig to a vertical orientation in the drilling rig derrick to be run through the drilling rig floor 12 into the sea or into the well bore below the rig.
  • the lower end of the pipe joint 11 terminates as a threaded pin and the upper end terminates as a connector 11a in the form of an internally threaded box.
  • Multiple pipe joints, such as the joint 11, are assembled to form a continuous flush joint pipe string of pipe that extends from the rig and through the sea to the sea bottom or into a well bore below the rig.
  • a pipe elevator (collar) 13 is attached to the upper end area 14 of an individual joint of the pipe to assist in bringing the pipe to the vertical running position.
  • the elevator 13 provides one of the attachment fixtures for the lines 16 and 17 used to lift and/or move the pipe to the vertical orientation. Additional positioning and restraint lines, such as the snub line 18 are attached to a fixture 20 that is removably secured to an attachment plate 21 bonded to the pipe. Once the joint 11 is in its vertical position, the elevator 13 supports the joint 11 vertically so that it may be added to a string of the pipe 22 extending through the rotary table 24 on the drilling rig floor 12.
  • One embodiment of the elevator 13 is a bolt-on collar with an internal annular projection. ( Figures 4, 6-12). This embodiment is not claimed.
  • the collar is bolted around an annular groove machined into the external surface of an internally threaded connector 11 a at the top of the joint 11.
  • the connector 11 a may be welded onto the tubular body of the joint 11 to provide an internally threaded box connection at the upper end of the joint or it may be otherwise secured to, or formed at, the end of the tubular body.
  • the groove is machined or otherwise suitably formed in the outer surface of the connector 11a. Machining is preferred to provide uniform surface contact between the elevator projection and the connector groove.
  • An embodiment of the elevator according to the present invention is a bolt-on collar having axially extending Keystone-shaped recesses that extend over corresponding Keystone shaped projections welded to the external surface of the internally threaded connector. ( Figures 13-16).
  • An elevator 25 is connected to the top of the assembled pipe string 22 extending below the rotary table.
  • the elevator 25 rests on the rotary table 24 to support the string 22.
  • the elevator 25 is identical to the elevator 13 that supports the joint of pipe 11 being added to the string.
  • the new joint 11 being added to the string is threaded into the string 22 by rotating the suspended string 22 with the rotary table 24 while holding the new joint stationary with a snub line 18 secured to the removable handling fixture 20.
  • the rotary 24 is rotated in a counterclockwise direction to cause the right hand threads of the joint 11 and the string 22 to engage.
  • the opposite end of the snub line 18 is secured to a stationary point (not illustrated) on the rig.
  • the lift lines 17 extending between the uppermost collar 13 and the top drive or traveling block of the rig are raised to lift the joint 11 and attached string 22.
  • Lifting the string 22 permits the lower collar 25 to be removed from the string.
  • the string 22, including the newly added joint 11 is then lowered until the upper collar 13 is resting on the rotary table 24 where it may support the entire string full. The process is repeated until the full string of pipe is run into the well.
  • Figure 4 illustrates cylindrical rotary table lugs 26 and 27 that extend downwardly from lifting pad eyes 28 and 29, respectively, of the elevator 13.
  • the cylindrical rotary table lugs 26 and 27 are received in openings 30 and 31 respectively formed in the top surface of the rotary table 24.
  • the engagement of the lugs 26 and 27 in the openings 30 and 31 transmits the rotary motion of the rotary table 24 to the collar 13, which in turn transmits the rotation to the connector 11a at the top of the joint 11.
  • Figure 5 illustrates a conventional rotary support table 35 having openings 36-39 of the type used to receive the rotary table lugs extending from the elevator 13.
  • FIGS 6 and 7 illustrate, in perspective view, two halves 13a and 13b of the elevator 13. This embodiment is not claimed.
  • Bolt holes 40-47 are provided in bolt ears extending radially from the two elevator halves for receiving bolts (not illustrated) used to securely clamp the elevator halves 13a and 13b about a pipe connection such as the connector 11a.
  • the rotary table lug 26 extends axially away from the elevator half 13a while the rotary table lug 27 extends axially from the collar half 13b.
  • Figure 8 illustrates the rotary lug 27 projecting from the bottom surface of the collar half 13b.
  • the elevator projection surface 51 engages the groove surface 52 to effect a large radially directed gripping force against the connector 11a.
  • the gripping force works with the surface friction between the two contacting surfaces to prevent relative rotation between the elevator and the connector during the process of adding joints to the string.
  • the projection surface 51 is slightly spaced axially from the groove surface 52a. The result is that the projection surface 51 b engaging the groove surface 52b supports a substantial amount of the vertical load imparted to the collar by the weight of the string 22. This embodiment is not claimed.
  • a modified elevator is illustrated in Figures 11 and 12. This embodiment is not claimed.
  • a projection 60 extending from the elevator 13 is adapted to be received within an annular recess 62 formed in the external surface of the connector 11a.
  • the projection 60 and recess 62 are similar to the projection and recess of Figures 9 and 10 with the exception of the change in dimensions and cross sectional profile of the components.
  • the dimension A of the projection 60 is less than the dimension B at the entry to the groove 62 so that the elevator 13 can be closed circumferentially about the connector 11a with the projection 60 received within the groove 62.
  • the recess 62 includes a reverse angle shoulder 64a adapted to engage and rest on a similarly angled surface 65 on the annular projection 60.
  • the inclined angles of the contact surfaces 64 and 65 cooperate with the weight of the string 22 to pull the elevator 13 radially inwardly to enhance the circumferential gripping force exerted by the elevator against the pipe connector 11a.
  • the inclined surfaces 64 and 65 also cooperate to hold the collar circumferentially about the pipe section 11a in the event of failure of the bolts or other parts of the elevator.
  • a feature of the form of the embodiment illustrated in Figures 11 and 12 is that the string weight pulls the elevator 13 into compression rather than forcing it into tension. Breakage or loss of the bolts holding the elevator halves together or partial breakage of parts of the elevator will not necessarily release the pipe from its support at the rotary table because of the trapping action provided through the mating inclined surfaces between the elevator projection and the connection groove.
  • the elevator illustrated in Figures 9-12 requires no radial protrusions on the external surface of the pipe joints and is inexpensive to fabricate and employ.
  • the system of Figs. 9-12 also permits the pipe to be handled without requiring an increase in the outside diameter of the flush joint pipe.
  • the elevator 13 described in Figures 9-12 is inexpensive to fabricate and one such elevator may be attached to each joint of pipe before the pipe is delivered to the location where it is to be run into the well. This procedure allows the elevator to be secured to each pipe joint in a controlled environment, ensuring that the bolts are probably torqued up and that the collar is properly secured to the connector 11a.
  • FIG 13 illustrates an elevator according to the present invention, indicated generally at 70, similar to the elevator 13 previously described but intended to be used with pipe joints having permanent external radial protrusions adapted to be received within accommodating recesses in the elevator 70.
  • the elevator 70 is designed for reuse at the well site. When an elevator 70 is removed from its support of the string 22, it is used to secure and remove a new joint from the storage rack and add the new joint into the string.
  • the elevator 70 is similar to the elevator 13 except that the central internal circumferential projection of the elevator 13 is replaced by Keystone shaped recesses 72 and 74 adapted to engage similarly shaped Keystone plates or projections 76 and 78 permanently secured to the external surface of the pipe section 11a.
  • Figures 15 and 16 illustrate elevator halves 70a and 70b in position about a pipe connector 11a to which Keystone projections 76 and 78 have been permanently welded.
  • Figure 17 is an elevation illustrating a Keystone plate that is welded to the external surface of the connector 11a.
  • Figure 18 is a top view of the Keystone plate, illustrating its arcuate shape, taken along the line 18-18 of Figure 17.
  • Figure 19 is a side elevation of the Keystone plate taken along the line 19-19 of Figure 17.
  • bolt holes 81-84 are provided on the broad part of the Keystone plate 76.
  • the bolt holes are used to secure handling fixtures that secure lines used in positioning and making up the pipe joints. The fixtures are removed before the joint is lowered into the well.
  • Three weldment areas 86, 87 and 88 are provided for providing welding contact lines for welding the Keystone plate 76 to the external surface of the connector 11a.
  • the lower end of the plate 76 is tapered as indicated at 90 to reduce the probability of hanging up the pipe joint to which it is secured as the pipe joint is lowered into the well.
  • Figure 21 illustrates welding W extending around the contact lines provided by the weldment areas.
  • the welding W along the internal weldment areas secures the Keystone plate 76 to the pipe connector 11a without requiring placement of welding material along the external surfaces 92 and 94 of the Keystone.
  • the external surfaces 92 and 94 are thus allowed to mate exactly with the engaging surfaces of the Keystone recesses in the elevator 70.
  • FIGS. 22-25 illustrate a permanent lug plate 21 to be welded to a pipe joint 11 to assist in handling and making up the pipe joint.
  • Figure 22 is a front elevation of the lug plate 21.
  • Figure 23 is a top view taken along the line at 23-23 of Figure 22 illustrating the curvature of the lug plate.
  • Figure 24 is a side view taken along the line 24-24 of Figure 22 illustrating the bottom taper 101 of the lug plate.
  • Figure 25 is a front elevation of the lug plate 21 welded onto a pipe joint 11.
  • the lug plate 21 is provided with four internally threaded bolt holes 102-105.
  • a weldment area 106 cut into the lug plate 21 provides an increased welding contact line for welding the lug plate to the pipe joint 11.
  • Welding W along the external lug edge and along the edges of the weldment area 106 is illustrated in figure 25 securing the lug plate 21 to a pipe joint 11.
  • Figure 26 is a cross sectional view illustrating a connecting fixture 20 secured to the lug plate 21 welded to the pipe 11. Two of four bolts 110 and 112 are illustrated seated in the bolt holes 104 and 105, respectively.
  • the connecting fixture 20 is provided with a circumferentially extending arm 20a and a pad eye plate 20b with a pad eye opening 20c.
  • the arm 20a assists in distributing reaction forces exerted through the restraining line 18 as the joint 11 being added to the string 22.
  • the pad eye 20c provides an attachment point for the restraining and/or control line 18 used in the positioning and/or makeup of the connection.
  • Figures 27 through 37 illustrate various steps in the transfer of a joint 11 from its storage location to a vertical orientation in preparation for being added to a string of pipe to be run into the well.
  • Figure 27 illustrates positioning lines 16 and 18 secured respectively to a connecting fixture 120 secured to a Keystone projection 76 and the connecting fixture 20.
  • the connecting fixture 120 is similar to the connecting fixture 20 and is bolted into place in the bolt holes 81-84 of the Keystone plate.
  • the lines 16 and 18 are illustrated lifting the joint 11 from its horizontal storage location in preparation to moving the pipe to the drilling rig floor.
  • Figure 28 illustrates the elevator 70 being positioned about the pipe 11.
  • the elevator 70 is suspended from lines 122 and 123 respectively connected to one of the two elevator halves 70a and 70b.
  • the lines 122 and 123 hold the elevator 70 in the open position illustrated in Figure 29.
  • a stop in the hinge 70c prevents the elevator from opening further to facilitate placement of the elevator about the pipe 11.
  • Figures 30 and 31 illustrate the elevator 70 loosely bolted around the pipe joint 11 prior to being moved axially into engagement with the Keystone projections 76 and 78.
  • Figures 32-34 illustrate the elevator 70 being rotated around the pipe joint 11 by releasing the line 122 and raising the line 123 to align the Keystone projections on the pipe with the Keystone recesses in the elevator.
  • Figure 35 illustrates the lift lines 17 being secured to the lift eyes 28 and 29 extending radially from the sides of the elevator 70.
  • the fixture 120 may be released from the Keystone projection 76 by removing the four bolts (not illustrated) holding the fixture to the key-stone projection.
  • the fixture 20 may be removed from the attachment pad 21.
  • Figures 36 and 37 illustrate the pipe joint 11 being moved to its vertical position with the use of the lift lines 17 and the snub line 18.
