Abstract EN
A novel approach of simulating hydromechanical coupling in pore-scale models of porous media is presented in this paper.
Parameters of the sandstone samples, such as the stress-strain curve, Poisson’s ratio, and permeability under different pore pressure and confining pressure, are tested in laboratory scale.
The micro-CT scanner is employed to scan the samples for three-dimensional images, as input to construct the model.
Accordingly, four physical models possessing the same pore and rock matrix characteristics as the natural sandstones are developed.
Based on the micro-CT images, the three-dimensional finite element models of both rock matrix and pore space are established by MIMICS and ICEM software platform.
Navier-Stokes equation and elastic constitutive equation are used as the mathematical model for simulation.
A hydromechanical coupling analysis in pore-scale finite element model of porous media is simulated by ANSYS and CFX software.
Hereby, permeability of sandstone samples under different pore pressure and confining pressure has been predicted.
The simulation results agree well with the benchmark data.
Through reproducing its stress state underground, the prediction accuracy of the porous rock permeability in pore-scale simulation is promoted.
Consequently, the effects of pore pressure and confining pressure on permeability are revealed from the microscopic view.
