摘　　要：煤层由于储层压力低、裂缝及层理发育,钻井过程中易发生钻井液漏失。本文合成了屏蔽暂堵剂,研制了防漏失钻井液体系并评价了其性能;现场使用该钻井液防漏失效果良好。Due to low reservoir pressure,cracks and bedding development,coal seams are prone to loss of drilling fluid during drilling.In this paper,a shielded temporary plugging agent was synthesized,anti-leakage drilling fluid system was developed and its performance was evaluated.The drilling fluid used on site had good anti-leakage effect.
