Based on the theories of continuous flow of porous media , rheology of silica gel solution and adsorption and migration of silica gel in porous media , a two - phase multicomponent mathematical model for oil displacement is developed with a numerical simulator , by which effects of the silica gel mass concentration , injection volume and flooding style on porosity , permeability and production response 在连续性介质渗流理论、硅胶溶液流变性理论、硅胶在孔隙介质内吸附和运移理论基础上,建立了一个两相多组分硅胶驱油数学模型,并开发了一个数值模拟器,定量模拟了硅胶质量浓度、注入体积和注入方式对孔、渗参数和开发效果的影响。
