ASP system transmission characteristics in the porous media

Chemical agents in liquid-liquid and liquid-solid interaction have the different loss In ASP Flooding resulting in chromatographic separation of them in porous media. In order to better describe and analyze the chemical agents’ transmission in porous media, using modified convection-diffusion equation with analytical solution processes the experimental data to get the equation of chemical agent migration lag coefficient and diffusion coefficient parameters. Experimental results show that for a single, different displacing agent but same flow conditions, the level of comprehensive diffusion and transmission lag are different, and difference leads to chromatographic separation; on the other hand, under the same flow conditions and that in ASP system the chemical agents diffusion of chemicals and integrated transmission delay is less than those of chemical agent in single system by polymer addition and competitive adsorption reasons.
