摘　　要：套管开窗侧钻是一种提高油田采收率的经济有效手段．2007年安塞油田开展了φ139．7mm套管开窗侧钻试验，通过强化井筒处理、优选开窗工艺、优化钻进工具组合和完井方式等一系列技术改进和应用，试验取得了成功。重点介绍了开窗侧钻工艺的现场试验情况。Casing cut window sidetracking is an economic and effective means for improving oilfield recovery. In 2007, Ansai Oilfield launched a φ139.7mm casing pipe cut window sidetracking test. The test was successful through intensifying shaft processing, prioritizing the window-cut technique, and optimizing drilling tools combination and well completion modes, and a series of technical improvements and application. This paper focuses on field test conditions of window opening sidetraeking technique.
