A FULLY COUPLED THERMO-HYDRO-MECHANICAL MODEL ASSOCIATED WITH INERTIA AND SLIP EFFECTS

ABSTRACT
The inertia and slip effects have a significant impact on the coal seam gas extraction. A fully coupled thermo-hydro-mechanical model is established in this study, which takes into account the influence of non-Darcy gas flow and Klinkenberg effect on the coal seam deformation and coalbed methane migration. The numerical result shows that the coalbed methane migration and transport evolution coal bed methane reservoir is not only dependent on the coal matrix deformation, gas pressure and gas adsorption, but also closely related to inertia effect and slip effect.
