Drilling stabilizer is an important tool for preventing well deviation in the drilling projects of petroleum, natural gas, and geological exploration. The mechanical performance of our drilling stabilizer is in accordance with API Spec 7.

There are 4 types of drilling stabilizer available:

a. Integral spiral stabilizer: the overall 3/4 spiral stabilizers are separately bottom hole type and drill collar type; the wear resistant materials for the working surface are diversified in many styles: carbide, diamond complex, wear resistant welding rod, low temperature brazing cemented carbide, etc.
b. Overall straight edge stabilizer
c. Roller type stabilizer
d. Spiral stabilizer with replaceable casings

Wear resistant materials for the working surface:

a. Carbide drill collar
b. Diamond complex
c. Wear resistant welding rod
d. low temperature brazing cemented carbide

Spiral stabilizer with replaceable casings

1. Internal thread
2. Stabilizer body
3. Spiral groove
4. Wear resistant part
5. External thread
