Tubing hanger lockdown mechanism

摘要

A completion component such as a tubing hanger includes a lockdown mechanism with an actuating mandrel that includes a positively acting anti-backout mechanism, which can be remotely deployed. The mechanism comprises a tooth on an inwardly biased retention ring carried by the mandrel, and positively engageable with a corresponding profile on the tubing hanger. Detent pins are outwardly biased by a tubing hanger running tool latch piston to hold the tooth and profile out of engagement during installation of the tubing hanger and setting of the actuating mandrel.
