摘要:
通过考察乳化液在多孔介质中的渗流规律,建立考虑乳化作用的复合驱数学模型。新模型既考虑水包油乳状液的形成可提高驱替相流度的作用,又考虑乳化降低残余油的机制;建立相对渗透率和相黏度的描述方式;将物理模型与数学模型结合,提出模型关键参数的获取方法。结果表明,复合驱中乳化可有效起到降水增油的作用,随着乳化性能增强,其降水增油能力也逐渐提升,但是增加的幅度逐渐减小。

Abstract:
Based on the study on emulsion flow behavior in porous media, a new mathematical model of alkali-surfactant-polymer (ASP) flooding was established. The mechanisms were considered that emulsion can improve the mobility of displacing phase and emulsion also can reduce residual oil saturation in the new model. Accordingly, the description of choosing new relative permeability curve and modifying viscosity of displacing phase after emulsification was established. A laboratory method was proposed to obtain the key parameters of the new model which combined the physical model with the mathematical model. The results show that emulsification of ASP flooding can reduce the water cut and increase oil output effectively. This effectiveness increases with the increase of emulsifiability, but the rate of increase decreases gradually.
Key words:  emulsification  mathematical model  ASP flooding  relative permeability curve  residual oil
