Non-rotating Stabilizer

Stabilizer is an important tool to prevent hole deviation in oil and gas drilling engineering. It is a one piece construction manufactured from high strength alloy steel (non-magnet steel optional), that prevents differential sticking of the drill string by stabilizing the BHA and keeping drill collars and drill pipes away from the borehole wall.

In that case,the deviation rate and azimuth change rate will follow the drilling plan, that can avoid “dog leg” from happening. Stabilizers can also increase the drilling speed and reduce the drilling cost.
