TIANHE Integral Blade Stabilizer (IBS) is a one piece rotating stabilizer which can be placed near bit or higher in the drill string. It is a one piece construction manufactured from high strength alloy steel (non-magnet steel optional), that prevents differential sticking of the drillstring by stabilizing the BHA and keeping drill collars and drill pipes away from the borehole wall. This reduces vibration, drill pipe whirl, and wellbore tortuosity; furthermore, the stabilization maintains drilling trajectory whether drilling straight, horizontal, or directional wells.

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.

TIANHE replaceable sleeve stabilizer consists of an integral mandrel and a sleeve.One mandrel series can be equipped with different sizes of sleeve for several holesizes. In order to match the drilling conditions, the sleeves can be easily changed on the rig floor during changing of hole size or wear surface.

We offer a complete range of Hardfacing to suit all drilling conditions. All TIANHE Stabilizers can be banded with the following hardfacings.

Lifting caps are tools for lifting of drilling tools, such as drill collars or stabilizers.
