Integral Spiral Blade Stabilizers
Integral Spiral Blade Stabilizers is divided into string type and near-bit type according to the position differently, there are many ways to increasing abrasive resistance, e.g. tungsten carbide, it owns high hardness and great toughness, high resistance, long service life, and so on.

Integral mandrel sleeve stabilizer
Integral mandrel sleeve stabilizers are made in two parts: One mandrel and one sleeve. The stabilizer is assembled by screwing the sleeve on the body and tightening these on the shoulder. The sleeve has been engineered to avoid any accidental unscrewing as to be easily replaced on rig

Non-Rotary Stabilizer
Non-Rotary Stabilizers is composed of two parts, one is mandrel, anther is sleeve. Between the sleeve and mandrel can be relation. To improve useful time, the inner wall of sleeve and the surface of mandrel OD were treated to use special anti-wear. In addition to this stabilizers have the function of general Stabilizers, as the sleeve and mandrel can be relative rotation, can play a role in reducing the torque, to make drill assembly reduce torque resistance during work.

Stabilizer with Back-reaming
The stabilizer with back-reaming is selecting the appropriate location and through special processing method to array few teeth as a cutting edge. In this way, this stabilizer can be played cutting when the process of drilling and pull out. During drilling process, forward and backward redressing can be played the role to repair and maintain the wall of a well, making trajectory of borehole as far as possible, more often than not leading to drilling difficultly because of hole shrinkage, and so on, at the moment, the forward and backward redressing of this stabilizer can be played cutting, to eliminate hole shrinkage phenomenon, thus saving time and costs for drilling.
