Abstract
A jig and method useful for coupling and/or uncoupling drill string sections. In some embodiments, the jig comprises a body having an outer surface for engaging a torqueing tool and a cavity extending from a first end to a second end of the body and an engagement means at the first end of the body. The engagement means may be dimensioned to non-rotationally engage an outer surface of a first end of a drill string section and the cavity may be sized to fit about a drill string section.
Claims9
A method for torqueing a sub to couple or uncouple the sub to a drill string, the sub comprising a body comprising a first coupling at a first end thereof and a second coupling at a second end thereof opposed to the first end, the method comprising:
- coupling a jig to the first coupling of the sub, the jig non-rotationally engaging the first coupling;
- engaging a first torqueing tool to an uphole end of the drill string;
- engaging a second torqueing tool to an outer surface of the jig;
- using one or both of the first and second torqueing tools, rotating the jig and the first coupling relative to the drill string to couple the sub to or uncouple the sub from the uphole end of the drill string;
- and
- coupling an additional drill string segment to the second coupling of the sub;
- wherein coupling the additional drill string segment to the second coupling of the sub comprises:
- non-rotationally engaging a wrench to the second coupling of the sub;
- uncoupling the first torqueing tool from the drill string and coupling the wrench to the first torqueing tool;
- uncoupling the second torqueing tool from the jig and engaging the additional drill string segment with the second torqueing tool;
- and
- using one or both of the first and second torqueing tools, rotating the additional drill string segment relative to the second coupling of the sub to couple the additional drill string segment to or uncouple the additional drill string segment from the sub.
A method for torqueing a sub to couple or uncouple the sub to a drill string, the sub comprising a body comprising a first coupling at a first end thereof and a second coupling at a second end thereof opposed to the first end, the method comprising:
- coupling a jig to the first coupling of the sub, the jig non-rotationally engaging the first coupling;
- engaging a first torqueing tool to an uphole end of the drill string;
- engaging a second torqueing tool to an outer surface of the jig;
- and
- using one or both of the first and second torqueing tools, rotating the jig and the first coupling relative to the drill string to couple the sub to or uncouple the sub from the uphole end of the drill string;
- wherein the second coupling of the sub is removable from the body of the sub.
