| 考察了辽河稠油脱沥青质油、胶质、沥青质及胶质与沥青质混合物对水包稠油乳状液油水界面张力的影响。 结果表明:在不同的水包稠油乳状液体系中，辽河脱沥青质油中饱和分、芳香分的存在能够促进胶质与乳化剂的相 互作用，降低体系的油水界面张力；辽河胶质与沥青质两者之间相互作用较弱，对油水界面张力影响很小;沥青质的 界面活性高于胶质和脱沥青质油,在水包稠油乳状液的形成过程中，沥青质起主要稳定作用;具有高芳碳率、低烷基 碳率、高芳香环缩合程度的组分在水包稠油乳状液中界面活性较高。 |

| Abstract: |
| TTie influence o( resin, asphaltene, deasphalted oil and resin-aspKaitene mixture on the interfacial tension of liaohe heavy oil-in-water emulsion was investigated. The results show that, in heavy oil-in-water emulsion with different emulsifiers， the existence of saturate and aromatic in deasphalted oil enhanced the interfacial activity of resin, so the oil-water interfacial tension is decreased. Hie interfacial activity of asphaltene is stronger than that of resin and deasphalted oil, and the interaction between resin and asphaltene canft enhance their interfacial activity, so asphaltene is the most important component of heavy oil in stabilizing the heavy oil-in-water emulsion. For the structural parameter, more aromatic carbon, little alkyl carbon and stronger condensation index of aromatic ring are helpful to enhance the interfacial activity of components. |
