Rotation release latch for a wellbore tool

摘要

A rotation release apparatus is provided for use in a wellbore tool to selectively couple a first wellbore tool member to a second wellbore tool member until the wellbore tool is lowered to a selected depth within the wellbore. The rotation release apparatus includes a coupling member secured to the first wellbore tool member, and a latch member secured to the second wellbore member. A cam member is secured to the coupling member to release the latch member from the coupling member when the wellbore tool is rotated about a longitudinal axis. The rotation release latching apparatus may be operated to couple the latch member to the coupling member by axial movement of the wellbore tool along a longitudinal axis.
