摘　　要：磁性导向钻井技术是指利用磁性导向仪器测量信号源和仪器位置的距离和方位信息,控制井眼轨迹在目的层连通或者平行,是现有的导向钻井技术的有效补充。目前,磁性导向钻井技术主要应用于钻成对平行水平井进行超稠油SAGD开采,钻水平连通井进行煤层气开采,同时该技术也可应用于地下可溶性矿物开采、救援井等方面。文章详细介绍了磁性导向钻井技术、磁性导向仪器及该技术的国内外发展现状,对该技术的发展趋势做了深入探讨。Magnetic guidance drilling technique can measure the relative position and orientation between signal and instrument used by magnetic tool, control well tracks connection or parallel in target formation, which is an effective complement of existing guidance drilling technique. Currently, Magnetic guidance drilling technique is mainly used in super heavy oil SAGD exploitation by drilling parallel wells and coal-bed gas exploitation by drilling horizontal interconnected wells, which is also used in underground soluble minerals exploitation, drilling relief well and monitoring well, and wellbores anti-collision etc. This paper presented magnetic guidance drilling technique and tool, and its status and developmental trend at home and abroad.
