摘要
位于川东高陡构造带的云安7井，因钻遇大断层倒转部位而被迫停钻。为实现勘探目标，从老井眼4000m处采用有线随钻测量仪、单点照相测斜仪侧钻，控制井身轨迹钻至井深5810m完钻，准确钻达地质目标靶区。该井是目前川东地区钻成的完钻井深双侧钻造斜点最深的定向井，取得了较好的技术经济效益和社会效益。
The drilling operations in Yun'an -1 well was interrupted because of confrontation of massive overthrust faults. In order to achieve the designed exploration purpose,a side track operation was conducted with cable measurement instrument and single shot instrument starting from the depth of 4,000m to the final depth of 5,810 m. The target point designed was accurately shot. This was the deepest horizontal well in the Eastern area of Sichuan Basin. A better than before technical - economical results and social effects were obtained in this well.
