欢17断块位于辽河盆地西部凹陷西斜坡欢喜岭油田西部。开发目的层为兴隆台油层。经过20多年的开发后,采出程度已高达48%,已进入开发中后期,油井供液差现象逐渐增多,目前必须想尽办法充分发挥这部分低产井井的潜力才能保证稳产。尝试实施捞油井注蒸汽及调整间开井间开周期和生产参数取得了良好成效,也为下步低产井的继续挖潜研究工作奠定了基础。
Huan 17 fault block is located in west of Huanxiling oil field west slope of western Liaohe Basin. Development of the target layer Xinglongtai reservoir. After more than 20 years of development, the degree of recovery has been as high as 48%. It has entered the middle and late stages of development. The phenomenon of liquid supply difference for oil wells gradually increases. At present, we must find ways to give full play to the potential of these low-yielding wells to ensure stable production. Attempts to implement oil injection well steam injection and adjust the open interval and production parameters between open well achieved good results, which also lays the foundation for further research on tapping low potential wells.
