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 82 0 86m ,闭合距 10 99 6 6m ,钻穿油层 5 6 2 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 4 5d 8h顺利钻完 32 0 0m的进尺 ,全井安全无事故 。The well Yun-2-Ping 1 is the first medium-radius horizontal well in Zhongyuan Oilfield.Its horizontal section length is 820.86 m,closured distance is 1099.66m,oil reservoir is drilled to 562.5m The well's horizontal section has many steps and needs turning azimuth.The akin horizontal well is very few in China.Through well prepare,the well Yun 2-Ping 1 with the depth of 3200m is finished drilling safely by only 45d and 8 hours.The vast economic benefit and social benefit are got.
