Stabilizer
Stabilizers are connected directly above the bits and between drill collars to stabilize bits, correct wells, measure increases or decreases in the inclination of the shaft, and prevent internment of drill collars under differential pressure. The stabilizer also keeps the drill strings centered in the well during well drilling, preventing fatigue and breakage of the drill collar and other drill strings.
◆Near-Bit Stabilizers
・Prevent the deflection of the bit
◆String Stabilizers
・Prevent the deflection of drill collars
・Reduce the contact surface of the well wall and the drill collars
・Ease the control of the direction of thewell
・Prevent the differential-pressure sticking of the drill collar
・Prevent the deflection of the bit

Sleeve Type
Sleeve replacement is recommended to use a stabilizer breaker
