RESUMO

Dynamic investigation of non-Darcy fluid flow is essential for achieving reasonable performance of any underground gas storage project. Using a robust open-source code based on Lattice Boltzmann Method (LBM), we simulated single-phase three-dimensional gas flow through random packed porous media as well as two real sandstone and carbonate called Bentheimer and Estaillades, respectively. The media and flow parameters such as Darcy permeability, tortuosity, beta coefficient, etc., are estimated and compared with previous experimental and numerical research surveys. Afterwards, diverse combinations of layered systems (hybrid cases) are constructed, to draw the variation pattern of beta factor with underlying pore structures which allow us to more accurately evaluate the effects of heterogeneity on the beta factor related to calculations and non-Darcy emerging investigation. The most heterogeneous hybrid cases belong to those with vertical patterns across the flow direction in which the early transition from creeping regime occurs.
