摘要
针对江苏油田部分油井水力压裂后层间水窜的问题,研究应用了桥塞挤水泥封堵工艺,使5口濒临报废的死井复活,措施有效率100％,累计增油1.96×104t。该工艺降低了作业难度,提高了封窜质量,为同类型油井的封窜提供了有益的借鉴。
Hydraulic fracturing is a main stimulation for low permeable reservoirs, which has been used extensively in the development of oilfield. In order to cope with the water channeling in some oil wells, the water blocking process of bridge plug cementing is studied and applied in 5 wells close to be rejected. The success rate is 100%, and 1. 96×104t oil has been produced totally. This process can make workerover easy and increase the quality of blocking, which sets a good example to the oil wells alike.
