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.
