摘　　要：为了解决塔河油田环保要求高、征地难度大、开发管理不便等难题,AT9井区首次采用丛式井钻井技术对碎屑岩油藏进行综合开发部署。针对AT9井区地质工程难点及丛式井直井段防碰的特殊要求,对井位选址、平台布局、井眼轨道及井身结构进行优化设计。详细介绍了钻井过程中采用的MWD随钻监测防碰、PDC+直螺杆复合钻井、钻井液等关键钻井技术,分析了丛式井组的技术合理性和开发经济性,验证了丛式井钻井技术在AT9井区的适用性,为塔河油田的经济高效开发进行了有效的探索。According to the geological engineering difficulties in AT9 well area and the special requirement of anti-bumping in the straight section of cluster wells, the designs of well location, platform layout, borehole trajectory and well structure are optimized.The paper introduces the key techniques of MWD anti-bumping, PDC＋straight spiral rod composite drilling and drilling fluid in drilling process, analyzes the technical rationality and the development economy of cluster well group and verifies the applicability of the cluster drilling technology in AT9 well area.
