Abstract

The traditional Shan-Chen pseudo-potential model has limitations, such as pseudo-velocity, density ratio limitation, and thermodynamic consistency defect. A method based on the improved Shan-Chen pseudo-potential model to study fluid flow in rock microfractures using the multiple-relaxation-time lattice Boltzmann method is proposed and validated using three arithmetic cases. The geometric characteristics (height and spacing) of the rough elements are varied to analyze the joint effects of rough elements and infiltration conditions on the
multiphase seepage in microfractures. Rough microfractures are simulated using regular rough elements of different shapes, including rectangular, trapezoidal, and triangular rough elements. With the increase in the rough element’s height, for the microfractures at the wall contact angle θ=145.5°, 117.2°, and 67.0°, the flow velocity decreases and then increases; for the θ=93.0° micro fissure, the fluid flow velocity decreases to stationary. With the increase in the rough element spacing, for the θ=145.5° micro fissure, the liquid flow rate continuously increases; for the θ=117.2°, 93.0°, and 67.0° micro fissures, the liquid flow rate continuously decreases. This study is expected to guide future researchers and engineering applications in terms of subsurface reservoirs.
