Abstract

To study the gas transmission characteristics in organic pores of rough shale reservoirs, firstly, considering the effect of roughness, adsorption layer, and stress sensitivity on fracture width variation, the effective fracture width model was established. On this basis, the real gas transport models of the adsorbed gas and bulk gas in rough reservoirs have been studied respectively, and the apparent permeability coupling model of rough microfracture of shale are proposed according to the difference of actual flow area. The validity of the proposed models was verified by comparing them with the simulation data, and the contribution of each migration mechanism to the total flow under different roughness and fracture width variation factors was analyzed. It is found that the formation pressure is proportional to the influence of roughness on permeability. When the initial crack width increases, the corresponding pore pressure decreases when the roughness has a greater influence on the proportion of slip flow. The influence of roughness on the Knudsen diffusion ratio and surface diffusion ratio will be greater when the initial crack width is smaller. In addition, if the initial crack width and pore pressure are constant, the greater the relative roughness, the greater the Knudsen diffusion ratio and surface diffusion ratio, and the smaller the slippage flow proportion.
