Coal Matrix Deformation and Pore Structure Change in High-Pressure Nitrogen Replacement of Methane

Coal Matrix Deformation and Pore Structure Change in High-Pressure Nitrogen Replacement of Methane

Coal matrix deformation is one of the main controlling factors for coal reservoir permeability changes in nitrogen foam fracturing. The characteristics and mechanism of coal matrix deformation during the process of adsorption/desorption were studied by isothermal adsorption/desorption experiments wi...
