摘要
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．
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.
