二元复合驱效果实验研究

The Experimental Studies on Effect of Binary Combination Flooding

采用聚/表二元复合溶液,分别对高渗、中渗、低渗三种岩心进行了驱替实验。实验表明二元复合驱能大幅提高采收率,并遏制含水率上升,分析了驱替效果特征。

Displace high permeability,middle permeability and low permeability cores separately with polymer/SAA.The results show that binary combination flooding helps EOR,keeps within limits to water content.Displace effects are analysed.
