摘　　要：针对新疆阜康白杨河煤层气矿区地层急斜、软硬互层、存在烧变岩层等问题造成的钻孔极易弯曲、坍塌等问题,采用空气潜孔锤钻井技术及无线电磁波随钻测井定向钻进技术,顺利解决了钻孔弯曲、塌孔、成孔难等施工难题,施工效率达到常规钻井速度的3倍以上,对于类似地层的煤层气井施工有借鉴意义。For steep formation,soft-hard interbeded layer and burnt rock exist in Baiyanghe coalbed methane mining area in Fukang of Xinjiang,drilling deflection and hole collapse are caused. Pneumatic DTH hammer and EM- MWD directional drilling technology were used to solve these difficult problems; the construction efficiency was more than 3 times than the general drilling speed.
