Numerical simulation of thermal - surfactant combination flooding for heavy crude reservoir 表面活性剂复合驱数值模拟研究
The effects of demulsifiers on interfacial tensions and membrane strength were studied for the model and effluence systems from the three - compound - combination flooding field . the interfacial tensions owned by the two - compound - combination system decreased but those owned by the three - compound - combination system increased with increasing the demulsifier concentrations . membrane strength decreased with the increase of demulsifier . the demulsification mechanism of demulsifier is suggested that demulsifier partially replaces the stabilizers and greatly decreases the intensity of interfacial film 针对模拟采出液和三元复合驱矿场采出液,研究了破乳剂对复合体系界面张力和膜强度的影响.破乳剂浓度增加,二元复合体系界面张力降低,而三元复合体系界面张力升高.破乳剂分子部分顶替乳化剂分子并显著降低了界面膜强度
