Product Information
Drilling Stabilizer is the important tools to prevent hole deviation for oil, gas and geological exploration and drilling. Stabilizer is widely used for angle buiding, drop angle, and hold angle, which is asse,bled on the drill stem to improve well hole quality and drilling speed, and to reduce drilling cost. According to structure, it is divided into integral spiral stabilizer, straight integral blade stabilizer, roller stabilizer, replaceable sleeve stabilizer, and variable diameter stabilizer. According to assembled location, it is divided into near-bit type and string type. Standard: API Spec 7-1.
The parameter of Drilling Stabilizer according to API Spec 7-1 specifications.
