Wangxuzhuang oil field has entered into high watercut and high production period with compositewatercut being above 90% and a rapid oil production decline.
Water flooding development in serious heterogeneous reservoirs will result in preferential seepage channels and injected water short-cycle to cause 98% of compositewatercut.
强非均质性油藏注水开发后形成优势渗流通道,综合含水率高达98%以上。

When the recovery of recoverable reserve is more than 80%, the single well fluid productivity rate will decline, the number of active Wells will reduce as the compositewatercut is more than 90%.
