NON-ROTATING STABILIZER

TIANHE non-rotating stabilizer (rubber sleeve stabilizer) is able to avoid blade wear and wall damage during drilling. The non-rotating stabilizer consists of mandrel, copper washer, rubber sleeve, spacer sleeve and self-locking lower sub.

During drilling, the non-rotating stabilizer transfers the torque by means of mandrel.  The rubber sleeve is sliding and moving relative to the mandrel and it plays a role  in stabilizing the well. A locking clutch (self-locking lower sub) will help to avoid  sleeve rotation during washover operation.
