摘要
侧明151井是中原油田φ139．7mm套管定向开窗侧钻小井眼技术攻关的第一口井。该井斜向器陀螺定向、φ139．7mm套管开窗、修窗一次成功，整个裸眼段φ116mm小井眼轨迹控制良好，完全达到设计要求，为中原油田老井侧钻、特别是小井眼套管定向开窗侧钻小井眼技术的提高打下了坚实的基础。文中详细介绍了该井的施工情况及技术特点。
Ceming 151 well is the flrst one applied slim hole technology with oriented window and sidetracking within φ139. 7mm casing in Zhongyuan Oilfield. The whipstock orientation by gyroscope, casing window and its repairing are accomplished only oncc. The trajectory conrtol of open hole section in φ116mm slim hole reaches to the design demand completely. On the hase, the slim hole technology for the old well sidetracking can be promoted,especially oriented window and slim hole sidetracking in small size casing. The paper introduces the drilling practice and technical characteristics.
