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.
Optional Stabilizers
TIANHE offers several options for IBS, in both alloy steel and
non-magnet materials:
- Spiral Integral Blade Stabilizer;
- Straight Integral Blade Stabilizer;
- Non-Magnet Integral Blade Stabilizer;

- Straight or spiral blades;
- Hardfacing type ;

- Body diameter required;
