套管开窗侧钻水平井技术在云平三井的应用

Application of Casing Windowing Lateral Drilling Technology in Yunping No.3 Well

套管开窗侧钻水平井技术应用于老井剩余矿层的挖潜和新井目的层缺失而开采上部已知目的层,对套损开发井的恢复生产和剩余矿层的综合开采效果明显;应用于多矿层、矿层不连续开发井,可有效提高单井产量和采收率。本文通过对云平三井开窗侧钻连通对接云普二井溶腔施工成功案例,对开窗侧钻技术进行了简要总结。

The casing windowing sidetracking horizontal well technology is applied to tap the potential of the remaining seam of the old well and to exploit the upper known target layer due to the lack of the target layer of the new well.The recovery production of the casing damaged development well and the comprehensive exploitation effect of the remaining seam are obvious;It can be applied to multi seam and discontinuous development wells,which can effectively improve the output and recovery factor of single well.This paper summarizes the windowing and sidetracking technology based on the successful case of Yunping No.3 Well windowing and sidetracking connection and Yunpu No.2 Well cavity construction.
