摘　　要：介绍了新疆宝浪油田 H4三维绕障阶梯式水平井的设计和施工情况 ,重点分析了该井侧钻后的增斜段、两水平段井眼轨迹控制的工艺技术和钻井液体系 ,并针对该井水平段钻井过程中钻具摩阻和扭矩过大、钻压传递困难等难点 ,提出了相应的技术措施 。Design and operation of H4 well, a three dimensional bypass staggered horizontal well which locates in Xinjiang Baolang Oilfield, are introduced in this paper. Well path control technology and drilling fluid system used in one building up and two horizontal sections are mainly analyzed. The corresponding measures according to existing difficulties, such as excessive drag & torque in horizontal section, are taken, which is helpful to drill similar wells.
