| 中文摘要:随着油田勘探开发的进一步深入，报废井、停产井越来越多，套管开窗侧钻技术是挖掘老区潜力，实现油田二、三次采油的有效方法。使用该技术对有价值的报废井、停产井进行开窗侧钻，不仅能充分利用老井筒，降低钻井成本、提高经济效益，而且能有效完善开发井网，提高增产效果。介绍了宁东油田第一口φ139.7 mm套管开窗侧钻水平井的开窗、定向施工情况，为今后在宁东油田实施此类定向井、水平井打下了一定的基础。 |

| Abstract:With the further development of oilfield exploration, there are more and more abandoned wells and shutdown wells. Casing cutting window sidetracking drilling technology is an effective way to realize tertiary and secondary oil recovery, by which old wells can be made full use and drilling cost can be reduced to improve economic benefit and can effectively perfected the development of well pattern. The paper introduced window cutting and the directional construction of a φ139.7mm casing cutting window sidetracking drilling for a horizontal well. |
