Hello experts, everyone. I am now ready to study the mechanism of gas-water competitive adsorption in shale / coal, and encounter two obstacles in the process of research. First, it is necessary to simulate the gas-water distribution characteristics of different pore models in kerogen cells, such as slit-type, circular, square, and triangular pores ( Fig.1 ). How to construct the pore morphology in MS software ? Secondly, for the constructed fracture-type pores, we want to realize the dynamic evolution process of gas-water displacement ( Fig.2 ). How do predecessors realize this process in MS software ?（This is the simulation process of predecessors：Firstly, a high-density methane molecular layer with a density of 0.2 g / cm3 was placed on the right side of the slit to diffuse methane into the coal slit, and then a constant pressure of 20 MPa was applied to the right baffle to compress the methane gas until the baffle position was balanced. After the methane is filled, a water molecular layer with a density of 1g / cm3 is placed on the left side of the slit, and a baffle is added on the left side of the water layer. The water molecular layer is compressed at a constant pressure of 30 MPa until the position of the baffle is balanced. After the water and methane molecules are completely filled, the middle baffle is removed, and the left pressure water baffle is kept at 30 MPa constant pressure, and the right methane baffle is kept at 30 MPa constant pressure. The two conditions of ' fixed ' and ' 20 MPa constant pressure ' are set respectively. The purpose is to simulate the two types of connected nanopores and blind end nanopores respectively. ）
