Replaceable sleeve stabilizer is made up of a body and a centralizer body, and its advantage is quickly replaced by centralizer body when the front is wear and failure. It is flexible and especially suitable to play directional well.
Applications:
Replaceable sleeve stabilizer is an important tool of oil, gas and geology exploration drilling engineering, prevent well deflection. It is mainly used in setting with arger in rigid drill collars and drilling pressure to make well deflection rate and orientation rate smaller, improving
