摘要
目前,钟市油田存在8个注水不见效的井组,极大地影响了整个钟市油田的开发效果。通过分析其构造、注采层位对应关系、注水强度等特征,发现注水不见效的原因主要有:油水井对应关系误判导致注水不见效和注水强度不够导致注水不见效等。通过重新建立注采对应关系、缩短注采井距以及提高注水量等方式进行分类调整治理并见到了一定成效,改善了钟市油田水驱效果,避免了成本的浪费。
There are 8 well groups that don't respond to water injection in Zhongshi Oilfield,greatly influencing its whole development efficiency.Through analyzing its structure feature,corresponding relation of injection-production layers and water injection intensity,the author determines that misjudgment for corresponding relation of oilwater wells and insufficient water injection is the main cause.Such measures as rebuilding injection-production corresponding relation,shortening injection-production spacing and enhancing injected volume are taken to improve its flooding effect and avoid waste of the cost.
