Non-rotating Stabilizer

Non-rotating Stabilizer
 
    The FXF type non-rotating stabilizer (rubber sleeve stabilizer )is a special tool in drilling to avoid blade wear and wall damage. During drilling, stabilizer transfer torque by depending on mandrel body, but rubber sleeve is sliding coordination which can be moved relatively, as a result, the sleeve plays a role of supporting of holewall. The sleeve is made of special elastic material and fixed by a latch clutch to prevent from rotating .

Float Valve Stabilizer

Float Valve Stabilizer
 
    Float valve stabilizer is mainly used in near bit type stabilizer while working for preventing from borehole deflection, when blowout or well kick takes place, the float valve stabilizer will automatically shut off inside bore of tool to avoid the accident. The tool owns features such as high strength, large flowing area, high temperature resistant and high pressure resistant, etc.

Spherical Stabilizer

Spherical Stabilizer
 

    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.

Variable Diameter Stabilizer

Variable Diameter Stabilizer
 
    Stabilizer is one of main drill tool assembly in hole guiding. During drilling in deviating and horizontal well , in view of workmanship, stabilizer OD is required to be equal or 1~2mm less than drill bit so that too small clearance between borehole wall and stabilizer usually causes stabilizer to be easily stuck during tripping out of hole.
    However, variable diameter stabilizer solves the problem which common stabilizer can not solves. During drilling in directional well, by use of differential pressure at nozzle produced by circulation of fluid among inside and outside of drill string, stabilizer stretch out supporting head to reach full hole so that stabilizer equipped with different drill tools to increase or angle drop or stabilize hole inclination. Meanwhile, when stop pump circulation, support head draws back so that stabilizer OD becomes small to improve tripping out smoothly.

Unbalanced Single-spiral Blade Stabilizer / Multi-

Unbalanced Single-spiral Blade Stabilizer / Multi-
 

    The unbalanced spiral blade stabilizer, relying on its structural unbalanced principle, during rotating of drill string, produces a centrifugal force toward weighted side. One time natural coincidence for restoring force with eccentric force whener drill tool turns a round. This would produce a large impact restoring force to straighten well-bore gradually. Therefore, both single-spiral blade stabilizer and multi-spiral blades stabilizer are ideal anti-inclination tool
