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。
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.
