摘　　要：在石油天然气钻井施工过程中,常常造成钻具接头磨损、偏磨及丝扣粘连,这是引起钻具损坏进而演化为井下事故的主要原因之一。同时由于钻具接头超磨,也容易造成钻具使用周期缩短甚至提前报废。为延长钻具使用寿命、减少事故发生,在实践中总结了一整套行之有效的修复方法:即:用气体保护焊接方法修复钻具接头;丝扣刷镀铜提高其表面质量,防止磨损和粘扣;用等离子喷焊耐磨带增加钻具接头耐磨性。实践证明这些方法可行且十分有效。In the construction process of oil and gas drilling, the joint drill wear, eccentric wear and threaded partial adhesion caused drilling damage and then evolved into the major mine accidents. At the same time the joint drill wear also easily lead to shortening the life cycle of drilling and even early retirement. To extend the drill life and reduce accidents, in practice, this paper summed up the whole set of effective rehabilitation methods： to repair the drilling with welding gas joint; threaded copper brush to improve the quality of its surface to prevent wear and gluing; to use plasma spray wear-resisting belt to increase the resistant of drilling joints. The practice proved that the method is feasible and very effective.
