Definitions

  • the field of the invention is tools that assemble and deliver tubular strings into a borehole and more particularly tools that allow circulation and movement of the string as it is assembled into the borehole.
  • the present invention provides a method of automatically gripping a tubular below an upset end or coupling and releasing the tubular mechanically or with the use of pressure or other devices such as motors and or gear arrangements.
  • the present invention connects to a traveling block and/or top drive and enables selective supporting and releasing of an“upset end” tubular (casing, tubing or drill pipe) by changing the load carrying element as well as sealing element, this allows supporting while running or pulling, filling, flow back and/or circulation.
  • the tubular supporting element of the invention is biased to the set position (collapsed below the upset). The bias can be created by the support element itself or by its own weight, springs or pneumatically.
  • the support element will open as it is lowered over a tubular to allow passing over the upset portion of a tubular and collapse to latch below an upset in the tubular once the upset is above the load element.
  • the current invention has the release system on the upper portion of the device thereby shortening the lower end to facilitate getting the tubular connection closer to the rig floor for ease of handling and connecting the next tubular member.
  • the current invention may also have an indicator device such as a sleeve to assist in identifying whether the device is in the latched or released position. Having the release at the upper end also facilitates easy connection to the top drive to use air, hydraulics or mechanical release.
  • the supporting element in the present invention is protected by lower entry housing and internal guide/shield members.
  • the internal guide/shield also acts as the expanding device of the supporting member while the entry member (Bottom Sub) also acts as the primary load element for the supporting member.
  • Figure 1 shows a cross-section of the invention
  • Figure 2 shows a cross-section of tire invention with supporting member open and the tubular being inserted
  • Figure 3 shows a cross-section of the invention supporting and sealing on a typical upset tubular
  • Figure 4 shows a cross-section view of the invention with tire supporting member gripping the tubular body below the upset;
  • Figure 5 shows a view of the“T” slot arrangement with the load carrying member in the set position
  • FIG. 5a is a view of the supporting element and the“T” slot arrangement between the supporting element and the release ring;
  • Figure 6 is an outside view of the invention with the indicator sleeve;
  • Figure 7 is a skeletal view of one of the arrangements of a releasing system under the indicator sleeve with the support member in the collapsed (set) position. In this position, the indicator sleeve is raised;
  • Figure 8 is a skeletal view of one of the arrangements of a releasing system under the indicator sleeve with the support member in the open (released) position. In this position, the indicator sleeve is lowered;
  • Figure 9 is an isometric view of the invention with a segmented support member.
  • the device has at its upper aid a Top Sub 1 that is threadedly connected to the Top Drive (not shown) at A.
  • the Top Sub 1 is threadedly connected and sealed at 20 to a Housing 2.
  • Housing 2 is threadedly connected to the Lower Entry Housing 3.
  • Housings 2 and 3 comprise an outer housing.
  • Inserted between and held in place by the Top Sub 1 and the Housing 2 is an Inner Protective Sleeve 5 that with the top sub 1 acts as a mandrel, this sleeve is sealed with the Housing 2 at its upper end by a seal 21.
  • the single piece expandable Supporting Element also referred to as a gripping assembly 4 is shown in the normal relaxed and collapsed position and is protected from external damage by the Lower Entry Housing 3 and from internal damage by the Lower Entry Housing 3 and Inner Protective Sleeve 5.
  • the Inner Protective Sleeve 5 is a key element that protects the Supporting Element 4 and provides the means of expanding the Supporting Element 4 to allow removal of the Tubular 15.
  • the Supporting Element 4 is attached to the releasing system through the Releasing Rings 6 and 7 with a “T” slot arrangement shown in FIG 4.
  • the Releasing Ring 7 is attached to Releasing Rods 8.
  • Releasing Rods 8 are arranged in axially drilled holes through Housing 2.
  • Releasing Ring 7 is attached to Releasing Ring 6 by a set of Balls 30 in mating grooves in Releasing Rings 6 and 7. This attachment allows relative rotation of the Supporting Element 4 and Releasing Ring 6 (through the“T” slot arrangement between Releasing Ring 6 and Supporting Element 4) shown more clearly in Figure 5. Allowing the rotation of the Supporting Element 4 is important to prevent w r ear and damage at internal surface 40 to extending lower end fingers which can constitute element 4 as the Tubular 15 may be rotating while the Upset U portion is being inserted or removed as can be more clearly seen in Figure 2.
  • the Supporting Element 4 is supported on its lower end at surfaces 70 and 90 by Entry Housing 3 at surfaces 60 and 80 respectively. These mating surfaces provide a key role in supporting the Support Member at a ideal diameter for complete supporting the Shoulder 35 of the Tubular 15 as can be clearly seen in Figure 2 (or the shoulder of a collar in a threaded and coupled connection as seen in oil field tubulars such as casing)
  • Seal Sub 9 which constitutes a sealing member is biased to the lower position by Spring 11, there is a Seal 26 to seal in the bore of Inner Protective Sleeve 5.
  • Seal Sub 9 has another Seal 27 for sealing inside a tubular. Seal Sub 9 is prevented from moving down by shoulder at 28 on the interior of Inner Protective Sleeve 5.
  • One of the releasing assembly is shown at the external upper end of Housing 2 and is formed by Piston 13, Sleeve 12 and Cap 14. Seals are shown at 22, 23, 24, and 25.
  • Piston 13 is attached to Rods 8 at B such that movement of the Piston 13 will move Rods 8.
  • Piston 13 and Rods 8 move upward causing Release Rings 6 and 7, which form a part of the releasing assembly, to pull the Supporting Element 4 upwards.
  • This upw'ard movement will cause the Supporting Element 4 to expand to its released position.
  • This expansion occurs when the Supporting Element 4 at surface 19 contacts the end of Inner Protective Sleeve 5 at surface 18 and the Piston 13 raises the Supporting Element 4 to its most upward and released position.
  • This releasing means is not attached to Housing 2 to allow it to rotate about Housing 2 should it be desirable to rotate the invention by the top drive. Chambers R and S can be attached to any pressure means available.
  • Supporting Element 4 can be biased to the low'est and latched position by the weight of all components Piston 13, Rods 8 Releasing Rings 6 and 7, Balls 30 and Supporting Element 4. Should additional bias be required pressure can be applied to Chamber S of “One Releasing Means”.
  • Supporting Element 4 and Lower Entry- Housing 3 can be constructed as shown in Figure 4 to allow the Supporting Element 4 to grip on the exterior of a tubular below the upset portion should there be one.
  • Supporting Element 4 can be made of several elements rather that the single piece illustrated in these Figures. Later in this discussion there will be mention of an Indicator Sleeve.
  • the Indicator Sleeve could be attached to the Piston 13 and made such that it would be over the exterior of the Housing 2 so that one could determine the operational position of the Supporting Element 4, in other words“Set” (collapsed) or“Released” (expanded).
  • FIG. 2 the device is shown with a Tubular 15 being inserted into the invention.
  • the upper end of the Tubular 15 initially pushes on the lower internal Surface 100 of the Supporting Element 4.
  • Tubular 15 will contact Seal Sub 9 at shoulder 28 forcing it upward against Spring 11.
  • Seal 27 will be in sealing contact with the upper end of Tubular 15 such that fluid can pass through the interior to and from the Tubular 15 and Top Drive (not shown).
  • FIG. 3 the device is shown in the set position with the Tubular 15 being supported at surface 35 by the Supporting Member 4 at surface 19.
  • Supporting Member 4 is supported at its lower end at surfaces 70 and 90 resting against surfaces 60 and 80 of the Lower Entry Housing 3.
  • the tubular would be supported by the slips at the rig floor, the top drive would be lowered until there is space between surface 35 of the Tubular 15 and surface 19 of the Supporting Element 4. This provides room for the Supporting Element 4 to be retracted. Pressure is then applied to chamber R which lifts Piston 13, Rods 8 Releasing Rings 6 and 7 and the Supporting Element 4. Supporting Element 4 is moved radially by the contact with surface 18 of the Inner Protective Sleeve 6 and surface 19 of the Supporting Element 4. In the released position the Supporting Element 4 is completely out of the path of the tubular and protected by the Inner Protective Sleeve 6.
  • Figure 4 is another configuration of the invention shown in Figure 1 except the supporting Surface 80 of the Lower Entry Housing 3 is eliminated thus allowing the Supporting Element 4 to move radially inwards until the gripping teeth on the interior contact the body of the Tubular 15 below the upset portion at Surface U.
  • pressure can be applied to Chamber S causing Support Member to contact the tubular Body at 50 with sufficient force to allow significant torque to be applied to the Tubular 15 as well as manipulation of the Tubular 15 into or out of the well bore.
  • Figure 5 and 5 A are views of the Supporting Element 4 and the“T” slot arrangement between the Supporting Element 4 and the Release Ring 6.
  • the Low'er Entry Housing 3 is not shown for clarity.
  • Figure 6, 7 and 8 are illustrations of a mechanical releasing system with a Sleeve 200 at the upper end and extending downward and over the Housing 2.
  • a Plate 300 with Pivots 201 forming a linkage.
  • a pin (not shown) forms the Pivot 201 and supports a Release Member 302.
  • Release Member 302 contacts the top of a groove in the Rod 8.
  • the Indicator Sleeve 200 rests on the top of the Releasing Member 302.
  • Figure 9 is a view of the Supporting Element 4 in the Released or expanded position as separate segments.
  • the Low'er Entry Housing 3 is not shown for clarity.
