INTEGRAL BLADE STABILIZER
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.
