Coupled Permeability Model of ASP Solution and Porous Media

摘要：

As the complicated system of ASP fluid flowing through porous medium,its componentshave physicochemical reaction with rock system．which not only affects the flowing of ASP system,butalso significantly changes the porous medium. Through the experiment of ASP system flowing throughporous medium. This paper discusses the different scales of ASPs components flowing character,analyzes the imoact of alkali concentration．polymer concentration and injection speed on the resistancecoefficient and residual resistance coefficient．obtains the regression equation to express the relationshipbetween residual resistance coefficient and equivalent shear rate in the middle shear rate domain,drawstlle conclusions as follows：with the shear rate increasing. The resistance coefficient and residualresistance coefficient increase at the beginning and then drop down;with the alkali concentrationincreasing. The residual resistance coefficient increases,but the increasing rate become slower while theresistance coefficient increases and its increasing rate becomes faster;In the middle shear rate domain(1s(-1)～100s(-1)). The rock residual resistance coefficient takes on logarithmic relationship with shear rate．
