Abstract :
This work is a primary achievement in studying the CO2 and N2–oil systems. To predict gas-liquid
relative permeability curves, a Shan-Chen type multicomponent multiphase lattice Boltzmann model
for two-phase flow through 2D porous media is developed. Periodic and bounce back boundary
conditions are applied to the model with the Guo scheme for the external body force (i.e., the
pressure gradient). The influence of relationship between cohesion and adsorption parameters and
the interfacial tension values in Youngʹs equation, pore structure (micro scan image derived porous
media response is compared with corresponding porosity and permeability ideal sphere pack
structure), and saturation distribution on relative permeability curves are studied with the aim to
achieve the realistic stable condition for the simulation of gas-liquid systems with a low viscosity
ratio.
