摘　　要：云2-平1井为中原油田第一口中曲率半径水平井,是中原油田在复杂区块提高原油采收率、加大开发力度的重要举措。该井水平段长820.86m,闭合距1099.66m,钻穿油层562.5m,水平段多台阶,大幅度扭方位,同类型的水平井在国内并不多见。通过充分准备,精密组织,仅用45d8h顺利钻完3200m的进尺,全井安全无事故,取得了巨大的经济效益和社会效益。Yun 2桺ing 1 is the first medium curvature well in Zhongyuan Oilfield, which is arranged to enhance oil recovery in complex fault blocks in Zhongyuan Oilfield. The horizontal interval is 820. 86m long, the closed distance is 1099. 66m, and the distance of drilled zones is 562. 5m. The drilling of the well was completed in depth of 3 200m with only 45d and 8 hours safely, getting high economic and social effectiveness.
