Spherical stabilizer is an important tool to control hole deviation when drilling a horizontal well or a deflecting well. The stabilizer can prevent from stucking in drilling and it can improve the quality of well and speed of drilling, which decrease the cost of drilling.The structure of spherical stabilizer as figure, the axial derection of the middle face of stabilizer is shorter, like ball, so call it spherical ball.
There are four kinds of abrasive resistant materials on the working surface of stabilizer.
(1) Insert tungsten carbide buttons on the surface.
(2) Insert diamond compound body on the surface.
(3) Low temperature welding tungsten carbide pieces.
(4) Hardfacing electrode on the surface.
The spherical stabilizer is one of new type tools which is used in horizontal and directional well to prevent hole inclination, improve drilling solution, improve drill tools service life and hole condition, cut off /scrape bore wall . Because of small size, simple structure, it is so applicable for horizontal and directional well .The guide inclined plane covered with polycrystalline compact and cutting edges covered with spherical tungsten carbide stud ,during stabilizer contacts with roughed hole wall , can cut or scraped off raised or irregular well wall, therefore, the spherical stabilizers are widely used in various of drilling operation.
Spherical Stabilizer: It is an important tool to control hole deviation when drilling a horizontal well or a deflecting well. The stabilizer can prevent from stucking in drilling and improve the quality of well and speed of drilling,which decrease the cost of drilling.
Features:
• To be manufactured from high strength 4145H heat treated material.
• Small size design with lower resistance.
• Various hardfacing is available i.e. Composite Tungsten Carbide Rod, Tungsten Carbide Inserts, Diamond Inserts, Geothermal.
• Special spec is available.
