Background
The stabilizer is an appliance, also called centralizer, which makes the axis of the drill bit as close to the central line of the drill hole as possible in order to keep the long and thin drill rod running stably, and is an important tool for preventing the change of well inclination in the exploration and development of petroleum and natural gas and the geological exploration drilling engineering. The stabilizing function is mainly to relieve radial and axial violent vibration of the elastic system of the drill string in the hole; the eccentric wear of the drill bit and the drill rod is reduced; the coring quality is ensured; well deviation is prevented, and the track quality of the well is improved. The stabilizer is of a relatively simple construction and is a large diameter joint with rib segments (straight or helical).
At present, the stabilizers commonly used on site are triple-spiral stabilizers, and most of the stabilizers adopt a certain number of hard alloy blocks embedded on spiral strips to increase the surface wear resistance. Because the helical strip is directly processed on the stabilizer body mostly, after wearing and tearing in the use, the external diameter of stabilizer diminishes, seriously influences the result of use, can't reach the requirement of design.
