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.
