Drilling tool stabilizer (also known as centralizer) is an important tool to prevent the change of well inclination in oil, gas and geological exploration and drilling engineering. It is widely used. Whether it is to increase inclination, decrease inclination section or stable inclination and leveling section, it is necessary to install several drilling tool stabilizers on the drill string to improve the quality of the well bore and the drilling speed and reduce the drilling cost. According to the structure, the drilling tool stabilizer can be divided into: integral spiral stabilizer, integral straight edge stabilizer, roller stabilizer, replaceable spiral stabilizer, variable diameter stabilizer, etc. According to the different installation positions, it can be divided into bottom hole type and drill string type.
