Abstract

A system including a connector system configured to couple a first tubular to a second tubular, including a sleeve configured to couple to an exterior surface of the first tubular, wherein the sleeve comprises a coupling feature, a lock ring configured to couple to the exterior surface of the second tubular and radially engage the coupling feature on the sleeve, and a support ring configured to energize the lock ring into engagement with the sleeve.

First claim

1 . A system, comprising:
a connector system configured to couple a first tubular to a second tubular, comprising:
a sleeve configured to couple to an exterior surface of the first tubular, wherein the sleeve comprises a coupling feature;
a lock ring configured to couple to the exterior surface of the second tubular and radially engage the coupling feature on the sleeve; and
a support ring configured to energize the lock ring into engagement with the sleeve.

2 . The system of claim 1 , wherein the lock ring comprises one or more protrusions configured to engage the sleeve.

3 . The system of claim 1 , wherein the coupling feature comprises one or more grooves configured to receive the lock ring.

4 . The system of claim 1 , wherein the lock ring rests within an annular groove on the second tubular.

5 . The system of claim 1 , wherein the sleeve comprises a first radial aperture that enables the tool to couple to the sleeve.

6 . The system of claim 5 , wherein the sleeve comprises a second radial aperture that enables the tool to extend through the sleeve and couple to the support ring.

7 . The system of claim 1 , wherein the sleeve and the first tubular are a one-piece structure.

8 . The system of claim 1 , wherein the support ring comprises a first angled surface and the lock ring comprises a second angled surface, and the first and second angled surfaces form an angled interface.

9 . The system of claim 1 , wherein the coupling feature comprises first threads and the lock ring comprises second threads, and the first and second threads engage one another to engage the first tubular to be compressed against the second tubular.

10 . The system of claim 1 , wherein the support ring comprises a first portion configured to contact and drive the lock ring and a second portion configured to couple to a tool.

11 . A system, comprising:
a mineral extraction system, comprising: a first tubular; a second tubular; and a connector system configured to couple the first tubular to the second tubular, comprising:
a sleeve configured to couple to a first tubular, wherein the sleeve comprises a coupling feature;
a lock ring configured to radially engage the coupling feature on the sleeve; and
a support ring configured to energize the lock ring into engagement with the sleeve.

12 . The system of claim 11 , wherein the coupling feature comprises one or more grooves configured to receive the lock ring.

13 . The system of claim 11 , wherein the lock ring rests within an annular groove on the second tubular.

14 . The system of claim 11 , wherein the sleeve comprises a first radial aperture that enables the tool to couple to the sleeve.

15 . The system of claim 14 , wherein the sleeve comprises a second radial aperture that enables the tool to extend through the sleeve and couple to the support ring.

16 . The system of claim 11 , wherein the support ring comprises a first angled surface and the lock ring comprises a second angled surface, and the first and second angled surfaces form an angled interface.

17 . The system of claim 11 , wherein the support ring comprises a first portion configured to contact and drive the lock ring and a second portion configured to couple to a tool.

18 . A method comprising:
landing a first tubular and a second tubular; coupling a tool to a sleeve and to a support ring; and driving a support ring axially with the tool to couple the first tubular to the second tubular.

19 . The system of claim 18 , wherein driving the support ring axially with the tool to couple the first tubular to the second tubular comprises driving a lock ring into contact with the sleeve coupled to the first tubular.

20 . The system of claim 18 , comprising rotating the first tubular with respect to the second tubular or the second tubular with respect to the first tubular to compress the first and second tubulars against one another.
