Drill stabilizer
Drilling tool stabilizer (also known as centralizer) is an important tool for preventing well deviation in oil, gas and geological exploration drilling engineering.It has a wide range of uses.Whether it is increasing or decreasing slope, it needs to be equipped on the drill string. Install a number of drilling tool stabilizers to improve the wellbore quality and drilling speed and reduce drilling costs. According to the structure, the drill stabilizer can be divided into: overall spiral stabilizer, overall straight edge stabilizer, roller stabilizer, interchangeable set of spiral stabilizer, and variable diameter stabilizer, etc.; according to the different installation positions, it can be divided into wells Bottom type and drill string type.
