RE-LATCH MECHANISM FOR WELLBORE LINER SYSTEM

摘要

A tool for releaseably coupling a first tubing to a second tubing in a wellbore has a tubular mandrel configured to couple to and be carried into the wellbore by the first tubing. A collet ring is in an interior of the mandrel and has a plurality of collets to engage the second tubing. A releasing piston is carried in the interior of the mandrel to change between supporting the collet ring such that the collets can release from the profile and allowing the collet ring to lock such that the collets are locked in the profile.
