Replaceable sleeve stabilizer is an important to prevent well deflection from changing in drilling of petroleum,natural gas, Geological exploration. In the case which equip more bigger rigidity, use stabilizer reasonably,make rate of well deflection changing and rate of position changing be little,to avoid in producing dogleg,and promote quality of well and speed of drilling, and reduce cost of drilling.
Replaceable sleeve stabilizer is made of main body, stabilizer sleeve,jacket.wear-resisting materials of stabilizer work face has 4 kinds: 1)inlay hard alloy string on surface 2) inlay diamond composite on surface 3)solder hard alloy piece in low tempreture on surface 4)build uo welding wear-resisting filler rod on surface.
