Description
The 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.
When ordering please specify:
● Casing size and weight;
● Hole size or required blade O.D.;
● Top and bottom connections.
