摘要(Abstract)：

在引进的UTCHEM数值模拟软件基础上 ,建立了非相态稀体系三元复合驱油机理数学模型 ,并利用所建立的数学模型对UTCHEM数值模拟软件进行了改进。对改进后的模型进行的模拟功能测试结果表明 ,模拟计算给出的水驱、聚合物驱和三元复合驱综合含水率变化曲线符合实际开采规律 ,三元复合驱比聚合物驱较大幅度地降低了油层剩余油饱和度 ,说明所建立的非相态稀体系驱油机理数学模型能够正确地模拟三元复合驱过程
A mathematical model that can describe the non phase behavior transformation ASP flooding enhanced recovery process mechanism is constructed in order to improve the simulation capability of chemical flooding simulator UTCHEM,and this mathematical model has been incorporated in UTCHEM.A simulator which can simulate the enhanced recovery process mechanism of non phase behavior transformation ASP flooding has been successfully developed.In order to verify the mathematical model,water flooding,polymer flooding and ASP flooding numerical simulation tests have been conducted ,their simulation production performance curves are in accord with their actual production performance curves respectively;and in contrast with polymer flooding,the residual oil saturation after ASP flooding are decreased to a great extent.The simulation test results indicate that the mathematical model have the capability to simulate enhanced recovery process of non phase behavior transformation ASP flooding.
