摘　　要：中 5 -平 61 5井是孤岛油田的一口调整水平井 ,井身剖面采用国内外罕见的上阶梯式 ,施工难度很大。施工中运用了调整井技术、水平井井身轨迹控制技术、FEWD地质导向钻井技术 ,钻井施工安全无事故 ,累计钻开油层 370m ,满足了地质开发要求。本井的成功施工为该地区薄油层调整水平井的施工积累了宝贵的经验。Zhong5-ping615 is an adjustment well in Gudao Oilfield. For its stair-stepping profile,the drilling operation become very difficult. In the drilling course,many techniques are applied,such as adjustment well technique,horizontal well trajectory controlling technique and formation evaluation while drilling technique etc.’so the drilling operation is safe and no accident. The drilled oil reservoir accumulated to a length of 370 meters,and meets the geologic and development requirments.The paper introduces the drilling techniques of the well.
