| 摘 要： | 以稠油为研究对象，考察了不同阳离子对稠油乳状液破乳效果的影响。测定了不同种类及含量的无机盐对稠油乳状液脱水率、黏度及油一水界面张力的影响。结果表明：二价离子ca^2＋，Mg^2＋可以促进破乳，一价离子Na^2＋对乳状液破乳影响不大，心对破乳有一定抑制作用。阳离子促进乳状液破乳能力由大到小依次为：Mg^2＋ca^2＋，Na^2＋，K^2＋。稠油乳液黏度、界面张力对破乳影响无规律性。 |
| 关 键 词： | 稠油乳状液 阳离子界面张力 破乳 |

| Abstract: | The influence of cations on demulsification of thick oil emulsion is investigated. The effects of different kinds and con- tent of inorganic salts on the dehydration rate and viscosity of emulsions and the oil-water interracial tension are studied. The results show that the presence of Mg^2＋and Ca^2＋ can effectively enhance the demulsification, Na＋ almost has no effect on demulsifieation, and K^＋has certain inhibitory effect on demulsifieation. It is verified that the demulsification of the cation down to this order： Mg^2＋, Ca^2＋, Na^2＋, K^＋. Viscosity and interfacial tension of thick oil emulsion have no regularity on the effect about demulsification. |
| Keywords: | heavy oil emulsion cation interfacial tension demulsification |
