摘要
以孤岛油田中一区Ng3聚合物先导试验区为原型建立概念模型,在此基础上通过数值模拟等手段,开展了聚合物驱油开发效果的影响因素分析,研究了静态因素和注聚合物因素对聚合物驱开发效果的影响。反韵律油层变异系数、正韵律油层变异系数和反韵律油层夹层距顶部位置是影响聚合物驱油开发效果的主要因素,原油粘度、夹层在生产井钻遇时射孔方式变化和聚合物用量对聚合物驱油开发效果也有一定的影响。
Ng3 polymer pilot test region of Gudao Oilfield was taken as prototypeto build concept model.Based on that,numerical simulationwas applied to analyze the factors influencing polymer floodingeffect,which mainly include static factors and polymer injectionfactors.The dominant factors influencing development effect of polymer flooding are variation coefficient of inverted layered reservoir,variation coefficient of positive rhythm reservoir,and range from the interbed to the top of the inverted layered reservoi...
