Description
Technical field
This utility model relates to the aid field of oil drilling, is specifically related to manufacture the non-rotating of a kind of oil drill rocker
Abrasionproof protector.
Background technology
In the exploration and development of oil gas field, protective casing is to bore a string high tensile steel tube opened under before high-pressure oil-gas layer,
After annular space being carried out sealing with cement, reinforcing well can be played, bear intrinsic pressure, isolation cavey formation and high pressure water layer, separate
Different pressure series of strata, to set up normal circulation of drilling fluid, are the installation of well-control equipment, blowout prevention, leakproof and suspension tail simultaneously
Pipe provides reliable guarantee, also has protective effect to production string, has laid good for follow-up drilling well and production testing operation
Basis.
During carrying out wellbore construction in protective casing, its drilling rod rotated is anti-with protective casing inwall helically track
Multiple constantly friction, this not only makes, and tool joint is the most levigate scraps, and more seriously makes the protective casing in many wells direct
Being worn through, make protective casing and well control facility all lose function, once the oil gas of high pressure zone is scurried out, and will appear from more out of control than well head
Even more serious disaster；It addition, skew easily occurs in drilling rod when carrying out production string well cementing operation, when causing operation, bored
Well offset, affect work efficiency.
