摘　　要：Based on the hybrid hypersingular integral equation-lattice Boltzmann methods (HHIE-LBM), the porosity and permeability evolution and evaluation process in anisotropic saturated porosity multiscale-multiphase-multicomponent (ASP-MS-MP-MC) structures under ultra high temperature and pressure conditions was analyzed on parallel CPU and GPU platforms. First, virtual physical models at multi-spatial scales (2 μm, 5 μm and 10 μm) were restructured by computerized microtomography technology and data. Second, using HHIE-LBM methods, the anisotropic porosity and permeability tensor at core level and pore level under ultra high temperature and pressure conditions were calculated. Third, the evolution and evaluation process of the porosity and permeability as a function of multi temporal spatial scales was investigated. Finally, the relationship between porosity and permeability and ASP-MS-MP-MC structures (micro-meso-macro-scale) was explored.Based on the hybrid hypersingular integral equation-lattice Boltzmann methods （HHIE-LBM）, the porosity and permeability evolution and evaluation process in anisotropic saturated porosity multiscale-multiphase-multicomponent （ASP-MS-MP-MC） structures under ultra high temperature and pressure conditions was analyzed on parallel CPU and GPU platforms.
