摘　　要：苏平14—13—36井是目前长庆苏里格气田水平段最长、视位移最大的水平井。完钻井深4876m，垂深3449．3m水平段长1200m．视位移1668．82m。苏平14—13—36井第一次斜井段施工失败，经过分析总结，运用水平井优化设计技术重新进行设计后，成功实现12％”井眼入窗，9％”套管顺利下到窗口，并运用常规钻具完成1200m水平段的施工。The Well Su-ping 14-13-36 is one with the longest horizontal section and largest apparent displacement in Sulige gasfield, with the completion depth of 4,876m, vertical depth of 3,449.3m, horizontal section of 1200m and apparent displacement of 1668.82m. The construction of inclined shaft section in Well Su-ping 14-13-36 was failed for the first time. Then, after analysis and sum-up, redesign with horizontal well optimization design technology, 121 4/2 wellbore entered the window successfully and 9 5/8 casing was lowered to the window smoothly. In addition, the construction in 1200m horizontal section was completed with conventional drilling tools.
