Abstract
ABSTRACT This paper present a pore-network model of two immiscible fluids in petroleum industry using lattice gas automata based on pores-and-throats representation of the heterogeneous porous media. The network has irregular geometry and pores or capillary segments of various different shapes and sizes distributed over the network in some irregular fashion, which is distinguishing two-dimensional networks. The main feature of this model is the mechanisms and mobilization in which immiscible carbon dioxide invaded the porous media occupied by oil could be simulated in dynamic condition process. The FHP-II (Frisch, Hasslacher and Pomeau, FHP) of lattice gas automata model is applied for simulation of immiscible displacement process of carbon dioxide to displace oil reservoir on the two-dimensional pore network model. The shape of the regions of displacing and displaced fluids mechanisms was simulated. The effects of grain sizes and shapes, and its distribution that represented by effective porosity and permeability in porous media on the displacement mechanisms and displacement efficiency are studied. This simulation also could predict the residual oil saturation and displacement efficiency of the processes. Comparison with laboratory experiment was also presented. Reasonable good agreement between the lattice gas automata simulation and laboratory experiment results were achieved. Keywords: Lattice Gas Automata, heterogeneous porous media, oil saturation, displacement efficiency
