高含水后期油井重复压裂选井选层方法探讨

Discussion about Well and Layer Selection for Refracturing at Late Period of High Water Cut Stage

针对杏北地区重复压裂井比例较高、压裂潜力变小、选井选层难度越来越大的实际,通过对“九五”以来重复压裂井的分析,总结出适合杏北地区重复压裂井优化选井选层的原则和重复压裂井的压裂时机,在实践中应用后,取得了较好的效果。

The proportion of refractured wells in north Xingshugang area is higher, the potential of refracturing becomes less, and it is more difficult to select wells and layers. Based on analysis of refractured wells since the ninth five-year-plan, the principles of optimal well and layer selection for refracturing in north Xingshugang area and the time for refracturing are summarized. The application results are fairly good in practice.
