摘　　要：姬塬油田Q011-35井组为长庆低渗透油藏的典型井组,在注水开发过程中层间、层内、平面矛盾突出,水驱效果评价难度大,传统评价方法效果差。按照动态监测资料与静态资料结合的模式,从平面、纵向、单砂体3个角度论证和分析,综合评价井组水驱效果,其评价结果较传统评价方法更加准确、合理。新的评价方法结果可信度更高,措施建议更具针对性,为今后评价低渗透油藏的水驱效果提供借鉴。Q011-35 is a typical well group in Changqing low permeability reservoir.Three contradictions are prominent in the process of water injection development,namely,within the layer,between layers and on the plane,which makes evaluation of waterflood effect difficult and traditional evaluation methods ineffective.In this paper,the effect of waterflood in the well group of low permeability reservoir is evaluated from three perspectives of plane,vertical and single sand body,by comprehensively demonstrated and analyzed with dynamic and static monitoring data.Compared with traditional methods,the evaluation results are more accurate and reasonable.The new method provides a reference for evaluating the waterflood effect of low permeability reservoirs in the future.
