| 摘 要： | 对胜利油田新滩区块稠油乳化降粘研究结果表明：稠油在乳化降粘配制O/W乳状液时，会形成部分W/O/W多重乳滴，这种多重乳滴的多少和性质与配制O/W乳状液的方法有关。当用纯稠油与活性水配制时，形成的多重乳滴少，其主要是中间油相与外水相油水界面膜的破坏。它的破坏对整个乳状液稳定性影响小。而利用高内相W/O乳状液用转相法配制O/W乳状液时，会形成较多的W/O/W多重乳滴。这种乳滴的破坏对乳状液稳定性有很大影响。

| Abstract: | Studying on reducing viscosity by emulsifying of Xintan heavy oil of Shenli oilfield, it is found that W/O/W poly phase emulsion dripping will be formed partly while preparing the heavy oil O/W emulsion. The quantity and property of such poly phase emulsion dripping is related to methods of preparing O/W emulsification. As the O/W emulsion is prepared with the pure heavy oil and active water directly, the poly phase emulsion dripping formed is a little. The reason is that the oil water interface film between middle oil phase and external water phase is damaged. It has little effects on the stability of the whole emulsion. However, much more W/O/W poly phase emulsion drippings are formed when preparing O/W emulsion by utilizing the method of phase inversion with high containing water W/O emulsion. It has great effects on the stability of the whole emulsion. |
