Abstract

We conducted experimental study on multi-phase flow behavior consisting of supercritical CO2and water in porous media. Grain size was changed as an experimental parameter in order to consider the effect on permeability characteristics. Using obtained experimental data such as discharge rate of fluids, differential pressure between inlet and outlet of sand column, we conducted a numerical simulation for laboratory-scale experiment in order to clarify permeability characteristics of supercritical CO2 in porous media. As relative permeability model, the extended Corey model that Nkrg and Nkrw as indexes were introduced into the original one was used. Through numerical analysis, the shapes of relative permeability curves that allowed us to reproduce CO2-water flow multi-phase behavior were optimized.
