摘　　要：研究了不同阴离子对稠油乳液破乳的影响,及对乳液黏度和油水界面张力的影响。结果表明:Br-能大幅度提高破乳效果,脱水率达到98%;Cl-次之;HCO3-使乳化程度加大,乳液黏度增大。Br-使稠油与水的界面张力远低于Cl-和HCO3-,界面张力和黏度都是影响破乳效果的因素。The effects of different anions on heavy oil demulsification, emulsion viscosity and oil-water interracial tension are studied. The results show that Brcan improve heavy oil demulsification greatly and the dehydration rate is 98%, C1- followes, HCO3- can make emulsification increase and enhances the emulsion viscosity. The interfacial tension with Br- is much lower than that with C1- and HCO3-. The interfacial tension and viscosity are both the factors that affect demulsification performance.
