摘　　要：杏平1井是集团公司2006年在安塞油田部署的一口重点试验井，钻井中形成了7个鱼骨状水平分支，累计钻井总进尺5068m，主水平段长1206m，目的油层内水平钻进总进尺3503m，首次突破了水平段1200m的长庆钻井记录，水平位移与垂深之比达到了1：1，16，多项指标达到全国领先水平，实现了主水平井眼及鱼骨状分支井眼重入等多项新技术，钻井实验取得了圆满成功。Xing-Ping No.1 well is a key test well arranged by the CNPC in 2006 in Ansai oilfield. Well drilling formed seven fishbone-shaped horizontal branches, with accumulated total footage of 5068 m, and principal horizontal interval is 1206 m long. The horizontal drilling footage within the objective reservoir is 3503m, for the first time as a breakthrough of the Changqing 1200m horizontal drilling records. Ratio of horizontal displacement to vertical depth is 1：1.16, with a number of indicators achieving the national leading level. New technologies like the re-entry of the main horizontal well and fishbone-like branch holes are achieved. The well drilling test has been a complete success.
