摘　　要：武M1-1井是中石油第1口煤层气多分支水平井。本文概括了武M1-1井钻井工艺的特点和成功的经验,深入剖析了钻井工艺中的不足,主要包括井身剖面设计与轨迹控制、井下摩阻/扭矩预测与控制、水平井与洞穴井对接、煤层井壁稳定性分析和井眼清洁等工艺。The Wu M1-1 well is the first coalbed methan （CBM） multi-branched horizontal well of the Petrochina. Based on real data of the Wu M1-1 well and field experience, this paper summarized drilling technique and success experience. Main content indudes design and control of well path, forecasting the drag and torque, intersection between two wells, analysis of well stability, cleaning well and so on.
