石油钻井在深井或超深井,特别是斜井钻进时,在钻杆柱上装入钻杆胶皮护箍可以隔离钻具与套管内壁的碰撞和对磨,从而延长钻具的使用寿命和减少套管内壁的磨损。目前,国内钻井现场多采用整体纯胶钻杆胶皮护箍,它存在强度差、装拆困难、位移严重、且容易破裂等缺点,常给钻井工作造 Oil drilling When deep well or ultra-deep well is drilled, especially when inclined shaft is drilled, the drill pipe rubber band hoop can be used to isolate the collision and the abrasion of the drill pipe and the inner wall of the casing pipe to prolong the service life of the drill pipe. Reduce the wear on the inner wall of the casing. At present, the domestic drilling site mostly uses the whole pure rubber drill pipe rubber band hoop, which has the disadvantages of poor strength, difficult assembly and disassembly, serious displacement and easy to rupture.
