SUBTERRANEAN TOOL WITH MULTIPLE RELEASE CAPABILITIES

机译:具有多种发布功能的地下工具

摘要

A subterranean tool can be actuated with one or more control lines for a hydraulic release. It can further be actuated with a shear release after a lockout feature for the shear release is defeated. The shear release features a lock that limits relative movement so that a shear member can be defeated but without a release. A dog limits relative movement in a wider groove where dog movement in the groove allows a shock absorbing feature to act to cushion the release as the shear member breaks. The relative movement is reversed to let a retaining ring drop out of the way into a groove that comes into alignment with it. The relative movement is reversed again to pull a sleeve out from under gripping collets that have previously failed to release and the tool releases from that point on the same way as the control line actuated release.
