中文摘要：
从实验和理论方面研究了多孔介质中乳状液渗流的规律及线性启动数学模型。在恒定压力下,通过不同乳滴的水包油型乳状液在不同渗透率的亲水性胶结岩芯中的渗流实验,得到了孔隙介质的渗透率随乳状液注入孔隙体积倍数增加而降低的变化规律;在不同的恒定压力下,通过乳状液渗流实验,得出了孔隙介质渗透率的降低幅度随着压力梯度的增加而减小的变化规律。提出了一种滞留乳滴的线性启动数学模型,采用方程积分与参数优化技术联合编程的计算方法,计算了乳状液在孔隙介质中的渗流规律,结果表明理论计算和实际测量值非常一致。
英文摘要：
The flowing rules of emusions through porous media and linear re-entrainment mathematical model from the point view of experiment and theory is studied.Under constant pressure,the flowing experiment with oil-in-water emulsions of different drop-sizes and hydrophilic cores of different permeabilities is conducted.That is concluded the permeability of porous media decreased with the increasing of porous volume.The flowing experiment with oil-in-water emulsions is conducted under different pressures,it is concluded that the higher the pressure gradient is,the smaller the lowering level of core permeability is.A linear mathematical model of re-entraining captured droplet in porous media is proposed.The flowing behavior with an algorithm combined the differential equation integration with parameter optimization tenchnique is calculated theoretically.The calculated results are alike with the experimental values.
