... reaching the saturation state, the micropores account for 51.87%, the mesopores account for 42.76%, and the macropores account for 5.37%. Because sandstone contains hydrophilic iron dolomite and clay minerals, it dissolves and adsorbs hydrophilic minerals after encountering water. The micropores gradually...

... and the v-type model. The diversity of models indicates that the relative permeability is influenced by multiple factors, and the applicability of each model is limited to some specific conditions. In conventional models, relative permeability is expressed as the function of the saturation of a certain...
