Non-rotating stabilizer
Non/rotating stabilizer (rubber sleeve stabilizer) is a special tool in drilling to avoid blade wear and wall damage. The non/rotating stabilizer consists of mandrel, copper washer, rubber sleeve, spacer sleeve and self-locking lower sub.
During drilling, the non/rotating stabilizer transfer the torque by means of mandrel, the rubber sleeve is sliding and moving relative to the mandrel, the rubber sleeve thus plays a role in stabilizer of well. A locking clutch (self-locking lower sub) will avoid sleeve rotation during wash over operation.
