Abstract

To study the gas transport characteristics in rough inorganic nanopores, the effective pore size models of circular and rectangular nanopores are established, considering the influence of the adsorption water film, rock surface roughness, effective stress and the shape of the nanopore section. On this basis, the gas flow patterns are coupled, and the gas transport models in circular and rectangular rough nanopore are established respectively. The effectiveness of this model is verified by comparing it with experimental data and other scholars' models. At the same time, the effects of roughness, cross-sectional shape, cross-sectional aspect ratio, and humidity on gas migration are analyzed. The results indicate that regardless of the cross-sectional shape, an increase in roughness will lead to varying degrees of reduction in the apparent permeability of micro and nano pores. When the pressure is small, the influence of roughness on the gas permeability of rectangular cross-section nanopores is greater than that of circular cross-section nanopores. As the pressure increases, the influence of roughness on the gas permeability of rectangular and circular cross-section nanopores tends to be the same. The influence of roughness on the water saturation of rectangular cross-section nanopores is less than that on circular cross-section nanopores.
