八面河油田近年注水开发工作的实践与认识

八面河油田油藏类型多样,开发方式多样,其中注水开发储量占全油田动用储量的61%。近年来,为改善注水开发油藏开采效果,保持产量稳定,油田针对各区块注水开发中存在的问题,在面4区面5块、广北8块、面14区沙三上采取了完善注采井网,注水井注氮调剖,水井动态调水以及改善水质等方面的工作,初步取得了较好的效果。

On Flooding Development of Bamianhe Oil Field in Recent Years

Bamianhe Oil Field is boasting of multiple kinds of reservoir and developing measures while reserves developed by flooding had accounted for 61% of the overall reserves accessible.In recent years,Ba Mianhe Oil Field has taken steps to address problems during block flooding in a bid to improve the effects of flooding exploration and maintain a stable output.The measures included enforcing the injection-production well pattern,implementing profile control of nitrogen injection,timely water regulating and water quality improvement in m4 area,m5 block,Guangbei 8block and the third member of m 14 area which had seen fairly well results emerging.
