Calculation of transport properties of an aqueous solution at the pore level
Alexander Yu. Demianov, Oleg Yu. Dinariev Schlumberger Moscow Research
Abstract:
A direct numerical simulation of a multicomponent aqueous solution transport, including salt ions and surfactants, was performed at the pore level. The mathematical model takes into account the formation of a double electric layer (DEL) and the adsorption of surfactants at the liquid-solid interfaces. Flows in real numerical models of porous media are considered. Based on the analysis of the results of calculations at the pore level (microscale), a theory is given and an integral computational and theoretical model is constructed to describe transport and thermodynamic properties at large scales (macro-scale), that is, the problem of thermodynamic and transport upscaling is solved.
Keywords:
multicomponent aqueous solution, micro-scale, macro-scale, upscaling problem, double electric layer, surfactant.
