摘要
分析了江苏油田 8a的捞油生产实践及 2 9口套管开窗侧钻井的有关资料 ,对苏北盆地第三系复杂小断块油田提高开发水平的措施进行了分析 ,认为在一定条件下采用套管、油管捞油及套管开窗侧钻能提高油井利用率及油田采收率 ,提高开发水平 ,从而提高经济效益 ,但套管开窗侧钻存在一定的风险 ,侧钻前要进行优选。
This paper analyzes 8 years' oil swabbing practice in Jiangsu oilfield, relative data of 29 side-tracking wells via milled window in casing, and measures for improving development in complex small faulted block oilfields in Tertiary of Subei Basin. It is thought that, under certain conditions, swabbing oil via casing an tubing and side-tracking can improve oil well utilization factor and recovery factor, thus improve economic revenue. However, side-tracking via milled window in casing has certain risks, and optimization must be done before side-tracking.
