US 2016/0258228 A1 · AUTOMATED LOCKING JOINT IN A WELBORE TOOL STRING

Abstract

An automated locking joint is provided. The automated locking joint can include a first member, a second member, a joint, a locking structure, and a positioning device. The joint can connect the first member with the second member. The second member can be pivotable about the joint relative to the first member. The locking structure can be positionable between a lock position that prevents pivoting of the second member about the joint and an unlock position that allows pivoting of the second member about the joint. The positioning device can automatically move the locking structure from the lock position to the unlock position or from the unlock position to the lock position.

Dependent claims

An automated locking joint, comprising:

a first member;
a second member;
a joint that connects the first member with the second member, the second member pivotable about the joint relative to the first member;
and
a locking structure automatically positionable between a lock position and an unlock position with respect to the joint based, at least in part, on a change in a pressure condition, the lock position preventing pivoting of the second member about the joint and the unlock position allowing pivoting of the second member about the joint.

2 more elements

A downhole system, comprising:

a first member;
a second member pivotally coupled with the first member;
a locking structure positionable between a lock position preventing pivoting of the second member about the first member and an unlock position allowing pivoting of the second member about the first member;
an automatic positioning device coupled with the locking structure such that the locking structure is movable from the lock position to the unlock position or from the unlock position to the lock position in response to a change in pressure communicated to the automatic positioning device;
and
a downhole assembly coupled with at least one of the first member or the second member, the downhole assembly including at least one of a drill string tool or a wire line tool.
