摘　　要：为评价泡沫复合驱的试验效果 ,预测泡沫复合驱的最终采收率 ,利用泡沫复合驱油三维多相多组分数学模型 ,对大庆油田北二区东部泡沫复合驱矿场试验进行了数值模拟研究 .跟踪拟合了试验区实施方案的开采动态指标 ,中心井区含水率跟踪拟合的相对误差为 4.48% ;利用拟合修正后的地质模型预测了试验区的泡沫复合驱油阶段采收率为2 2 .74% ,中心井区总采收率为 67.3 6% .应用结果表明 :泡沫复合驱三维多相多组分数学模型具有较强的实用性 .The numerical simulation study has been conducted in order to evaluate the enhanced oil recovery effects and predict the ultimate oil recovery for ASP +Foam combination flooding pilot project in Daqing Oil Field. The simulator used for the study has modeled the main displacement mechanisms and physicochemical phenomena in ASP+Foam combination flooding. The production history of pilot has been successfully matched with field results, and the history matching result's relative error of water cut in central well region is 4.48%, the satisfactory matching result has been attained; the performance prediction results have been given based on the good history matching result. According to the numerical simulation results, the oil recovery factor in central well region which is due to ASP+Foam flooding is 22.74%, and the accumulative oil recovery factor in central well region is 67.36%. The numerical simulation results indicate that the numerical simulation method can provide a powerful studying and evaluating tool in large scale application of ASP+Foam combination flooding.
