Definitions

  • the present disclosure relates to an apparatus for longitudinally moving a tubular and a method for running a tubular.
  • heavy tubulars extend downward from the platform and may be supported by engagement with a landing string.
  • the landing string may be provided by drill pipe or other high-tensile tubulars.
  • Such landing strings are often required to support a heavy load, such that traditional running systems, which generally employ slips or bushings to hold the tubular by engaging the outer diameter thereof, are inadequate.
  • landing strings are typically lowered by engagement with an upset (i.e., a shoulder) on the tubular body of the landing string.
  • an upset i.e., a shoulder
  • One way to do this is to employ dual-upset tubulars, allowing the tubular to be lowered by engaging one upset with the elevator and the second with the spider.
  • Another common method shuttles or circulates a pair of elevators to ensure that only the upset is engaged, thereby obviating the need for special dual-upset tubulars.
  • the first elevator begins suspended by the bails, while the second elevator acts as a spider, resting on the rotary table and supporting the landing string by the upset of the uppermost tubular of the landing string (i.e., the most recently run-in segment).
  • the first elevator engages a new tubular segment, positions it with the top drive, and the top drive makes it up to the exposed box of the landing string.
  • the slips or bushings of the second elevator are then disengaged from the upset and the second elevator is removed; thus, the weight of the landing string is transmitted through the new tubular segment to the first elevator.
  • the first elevator then lowers until it abuts the rotary table, and, as such, now acts as a spider.
  • the bails are then switched to the second elevator, which engages another new tubular segment, and the process is repeated.
  • US 2004/055421 A1 describes a die insert for gripping oil field tubular members in tubular handling systems such as power tongs, slips, safety clamps and the like.
  • the die insert has a gripping surface comprising a backing surface adapted to contact the tubular member.
  • the backing surface may be smooth or it may have a series of teeth formed thereon.
  • the backing surface further has a granulated particle coating applied thereto which forms the gripping surface and includes a refractory metal carbide.
  • WO 97/49944 A1 describes a slip die with a substantially smooth pipe contact surface employed in a conventional slip assembly as a primary mechanism for gripping pipe.
  • a second conventional slip assembly with conventional dies having penetrating die teeth on their contact surfaces is employed as a secondary gripping mechanism to automatically grip the pipe in the event the primary mechanism loses its grip.
  • US 2004/074647 A1 describes an apparatus for, and method of, lowering items from a drilling rig to a well located below it through the use of a landing string comprised of drill pipe having an enlarged diameter section with a shoulder, in combination with upper and lower holders having wedge members with shoulders that engage and support the drill pipe at the shoulder of the enlarged diameter section, the shoulder of the drill pipe and the shoulders of the wedge members being rotatable with respect to each other.
  • US 6 237 684 A1 describes a support table with an upwardly extending tubular neck engaging the lower surface of the upper connector of the string to support the string while resting on a floor-level support.
  • the neck is small enough for an elevator to close around the neck and still engage the outer portion of the lower surface of the connector.
  • the support table is split into separable parts for opening to install and remove it from around the string.
  • an apparatus for longitudinally moving a tubular comprising a first tubular engagement device suspended from a rig and including a plurality of first gripping assemblies spaced apart and defining first channels therebetween.
  • the first gripping assemblies are configured to engage the tubular to support the tubular.
  • the apparatus also comprises a second tubular engagement device including a plurality of second gripping assemblies spaced circumferentially apart and defining second channels therebetween.
  • the second gripping assemblies are configured to engage the tubular to support the tubular.
  • the second tubular engagement device is configured to engage the tubular while the first tubular engagement device is also in engagement with the tubular.
  • a method for running a tubular comprises engaging an upset of the tubular with an elevator, moving the tubular by vertically moving the elevator, engaging the upset of the tubular with a spider while still engaging the upset of the tubular with the elevator, and disengaging the upset of the tubular from the elevator, such that the upset is supported by the spider.
  • first and second features are formed in direct contact
  • additional features may be formed interposing the first and second features, such that the first and second features may not be in direct contact.
  • exemplary embodiments presented below may be combined in any combination of ways, i.e., any element from one exemplary embodiment may be used in any other exemplary embodiment.
  • FIG. 1 illustrates a perspective view of an exemplary running system 10, according to an embodiment described.
  • the exemplary running system 10 may be particularly useful for running landing strings; however, it will be appreciated that the running system 10 disclosed herein may be equally applicable to running, lowering, raising, making-up, breaking-out, or otherwise moving any type of tubulars for any purpose.
  • the running system 10 generally includes first and second tubular engagement devices 12,14.
  • the first tubular engagement device 12 is movable, and may be referred to as an elevator 12.
  • the second tubular engagement device 14, on the other hand, may be stationary and may be referred to as a spider 14.
  • the elevator 12 includes a body 16, which may have a generally cylindrical shape and opposing flats 18, 20. Ears 22, 24 for engagement with bails (not shown) extend from the flats 18, 20, for example outward, such that the elevator 12 may be suspended from the rig ( e . g ., via a traveling block and/or top drive, not shown) and movable vertically toward or away from the spider 14.
  • the body 16 defines a central bore 26 therethrough, in which gripping assemblies 28, 30, 32, 34 are positioned.
  • gripping assembly is intended to be broadly defined to include any configuration of one or more slips, bushings, or any other device(s) used to engage a tubular, whether including teeth or not.
  • Channels 36, 38, 40,42 are defined by the bore 26, between adjacent gripping assemblies 28, 30, 32, 34.
  • each of the gripping assemblies 28, 30, 32, 34 may generally include a tapered housing 44, a bracket 46, a piston 48, and a wedge 50.
  • wedge is intended to be broadly defined to include slips, bushings, bushing segments, or any like structures capable of applying a gripping force to a tubular, whether including teeth or not.
  • the wedge 50 is free from teeth or other marking structures.
  • the tapered housing 44 is generally positioned in the bore 26 and bears on the body 16; further, the tapered housing 44 may be integral with a remainder of the body 16 and/or may be coupled thereto.
  • the tapered housing 44 is tapered such that it extends radially inward, proceeding downwards, and provides a channel 45 in which the bracket 46 and piston 48 are at least partially disposed.
  • the bracket 46 is moved in the channel 45 by movement of the piston 48.
  • the piston 48 may be moved or articulated by a hydraulic assembly, as is well-known in the art.
  • the piston 48 may be driven by pneumatics, motors, springs, linkages, combinations thereof, or the like.
  • the bracket 46 may be configured to transmit longitudinal, for example, upward, force on the wedge 50, to disengage the wedge 50 from a tubular (not shown), as will be described in greater detail below.
  • four gripping assemblies 28, 30, 32, 34 are shown, it will be appreciated that fewer or additional gripping assemblies, for example, two, three, five, six or more gripping assemblies, may be used.
  • the spider 14 includes a body 100, which may be generally cylindrical in shape and may have an increased-radius shoulder 101 defining at least a portion of the top of the body 100.
  • the shoulder 101 of the body 100 defines flats (three are visible: 102, 104, 106) on its outer diameter for engagement with various tools or other structures, as will be described in greater detail below. Further, the shoulder 101 may define a landing surface 108 on the upper side thereof.
  • the body 100 may also define a bore 103 extending axially therethrough, for receiving a tubular (not shown). Proximal the top of the bore 103, the body 100 may define an annular seat 105, which is recessed from the landing surface 108.
  • the body 100 may be split, as shown, defining two or more generally arc-shaped segments 109a, 109b.
  • the segments 109a, b may be held together by an interior surface defined in the rotary table (not shown), as is known in the art. In other embodiments, however, other structures such as a retaining collar or the like may be used to secure the position of the body 100. Additionally, in still other embodiments, the segments 109a,b may be coupled together via a hinge (not shown) or any other coupling mechanism.
  • Gripping assemblies 110, 112, 114, 116 may extend upward from the landing surface 108 and the seat 105 and inward from the bore 103.
  • Channels 118, 120, 122, 124 are defined between adjacent gripping assemblies 110, 112, 114, 116.
  • each gripping assembly 110, 112, 114, 116 may include a tapered housing 126, a bracket 128, a wedge 130, and a piston 132. Further, the housing 126 provides a channel 135 therein for guiding longitudinal movement of the bracket 128.
  • the bracket 128 is coupled to the wedge 130 and may be configured to transfer longitudinal force from the piston 132 to the wedge 130, for example, to raise or lower the wedge 130 into or out of engagement with a tubular (not shown).
  • the piston 132 may be driven to move the bracket 128 by pneumatics, hydraulics, motors, mechanical linkages, springs, combinations thereof, or the like.
  • FIGS 2-8 illustrate an exemplary operation of the running system 10, whereby a sequence of the elevator 12 engaging and moving a tubular 200, lowering the tubular 200 through the spider 14, transferring load to the spider 14, and disengaging from the tubular 200 is illustrated. It will be appreciated that this sequence may be reversed, or otherwise rearranged.
  • the gripping assemblies 28, 30, 32, 34, particularly the wedges 50 are configured to releasably engage the tubular 200.
  • the wedges 50 may be drawn downward by engagement with the tubular 200 or by driving the piston 48 downward, as described above.
  • the tapered housing 44 is generally prevented from moving radially outward by the body 16, and thus the wedges 50 sliding downward causes the wedges 50 to move inward, toward the tubular 200, until the wedges 50 securely engage the tubular 200.
  • the bails (not shown) coupled to the ears 22, 24 may thus enable the rig (not shown) to carry the weight of the tubular 200.
  • the tubular200 is generally free from engagement with the elevator 12 in the channels 36, 38, 40, 42.
  • Figure 4 illustrates a perspective view of the running system 10, with the elevator 12 and the spider 14 being moved vertically into close proximity with one another, according to an embodiment described.
  • the gripping assemblies 28, 30, 32, 34 of the elevator 12 may be angularly aligned with the channels 118, 120, 122, 124 (channels 120 and 122 are viewable in Figure 4 ) of the spider 14, while the gripping assemblies 28, 30, 32, 34 engage the tubular 200 and transmit its weight via the body 16 of the elevator 12 to the rig (not shown).
  • the spider 14 generally does not engage the tubular 200 to bear its weight, although in some instances, it is contemplated that the spider 14 may provide guidance for the lowering of the tubular 200.
  • the elevator 12 is lowered toward the spider 14 while engaging an upset (not shown) of the tubular 200, as will be described in greater detail below.
  • the body 100 of the spider 14 is surrounded by the rotary table 134.
  • the rotary table 134 defines a generally rectangular inner surface 136, with the generally cylindrical body 100 being inscribed therein.
  • the flats 102, 104, 106 flats 104 and 102 are viewable in Figure 4 ) of the shoulder 101 of the body 100 may bear on the inner surface 136.
  • the segments 109a,b of the body 100 may be restrained from separating by the rotary table 134, thereby preventing the gripping assemblies 110, 112, 114, 116 of the spider 14 from moving radially-outward.
  • the body 100 of the spider 14 may, in some embodiments, not be segmented, may be hinged, and/or may include more than two segments.
  • Figures 5 and 6 illustrate perspective and top views, respectively, of the running system 10, showing the elevator 12 transferring the load of the tubular 200 to the spider 14, according to an embodiment described.
  • the gripping assemblies 110, 112, 114, 116 extend upward, toward the elevator 12 and are sized to slide axially and fit at least partially in the channels 36, 38, 40, 42 of the elevator 12.

  • the elevator 12 is thus received into the spider 14, such that, in an exemplary embodiment, the elevator 12 rests on the landing surface 108 ( Figure 4 ) of the spider 14.
  • the enmeshed gripping assemblies 28, 30, 32, 34 and 110, 112, 114, 116 of the elevator 12 and the spider 14, respectively, are thus both positioned about the tubular 200 at approximately equal axial locations.
  • the gripping assemblies 110, 112, 114, 116 of the spider 14 may be engaged when the elevator 12 comes into proximity with, for example lands on, the landing surface 108 ( Figure 4 ).

  • the gripping assemblies 110, 112, 114, 116 may then engage the tubular 200, for example, the upset (not shown) to which the gripping assemblies 28, 30, 32, 34 of the elevator 12 are also engaged, though at different circumferential locations about the tubular 200.
  • the gripping assemblies 28, 30, 32, 34 of the elevator 12 may be disengaged.
  • the elevator 12 releases the tubular 200, and the weight of the tubular 200 is transferred seamlessly to the spider 14.
  • the elevator 12 may be raised upwards, may have a hinge (not shown) that can open to allow the elevator 12 to be laterally removed, or may be otherwise configured for removal.
  • this enmeshing of the gripping assemblies 28, 30, 32, 34, 110, 112, 114, 116 allows the spider 14 and the elevator 12 to engage a single upset, transfer the load between the two ( e . g ., from the elevator 12 to the spider 14), and release the elevator 12 so that it may be used to engage another tubular (not shown), to repeat the engaging and lowering process.
  • FIGs 7 and 8 illustrate perspective and top views, respectively, of the spider 14 engaging the tubular 200, according to an embodiment described.
  • the elevator 12 e.g., Figure 6
  • the gripping assemblies 110, 112, 114, 116 of the spider 14 engage and maintain the position of the tubular 200, while the rotary table 134 maintains the radial position of the body 100, and thus of the gripping assemblies 110, 112, 114, 116.
  • the gripping assemblies 110, 112, 114, 116 of the spider 14 are illustrated as extending upward for being received into the channels 36, 38, 40, 42 of the elevator 12, while the gripping assemblies 28, 30, 32, 34 are generally disposed within the bore 26 of the elevator 12.

  • the upset 324 may be capable of withstanding greater tensile forces than the tubular body 326 and transmitting such axial forces to the gripping assemblies 301, 302. Accordingly, the upset 324 may represent an area desirable for the gripping assemblies 301, 302 to engage, to avoid slip crushing the tubular 200.
  • the lower interior surfaces 316, 320 may engage the tubular body 326, as shown. Accordingly, some of the axial load of the tubular 200 weight is transmitted via the radial gripping force applied by the gripping assemblies 301,302 onto the tubular body 326.

  • Figure 10 illustrates a method 400 for lowering a tubular, according to an embodiment described.
  • the method 400 may proceed by operation of the running system 10 and/or the tubular engagement device 300 described above with reference to Figures 1-9 and may be best understood with reference thereto.
  • the method 400 includes engaging an upset of the tubular with gripping assemblies of a first tubular engagement device, as at 402. More particularly, in at least one embodiment, such engagement may include simultaneously engaging the upset and a body of the tubular to support a weight of the tubular via engagement with both the upset and the body.
  • the tubular supported by the first tubular engagement device, as at 402 may then be lowered into and made-up to a tubular string, such that the method 400 includes supporting the weight of the string of tubulars with the first engagement device.

  • the method 400 may also include receiving gripping assemblies of the second tubular engagement device into channels defined between gripping assemblies of the first tubular engagement device, as at 406.
  • the method 400 may also include engaging the upset of the tubular with the gripping assemblies of the second tubular engagement device, as at 408.
