【Abstract】 Based on the analyses of three-phase medium system and ternary pore-fracture structures in coal reservoirs, the mechanism of the description, diffusion and layer flow of the coal bed methane, also the experiment or trial methods of coal reservoir permeability were discussed. Especially, the importance of the numerical simulation on studying coal reservoir permeability are emphasized.更多还原
