Study on nonlinear seepage characteristics of N2/CO2 displacing CH4 in coal seam at low and medium pressure

The geological structure of coal seams in China is complex, with high degree of metamorphism and low permeability, making it difficult to extract gas from the original coal seams. As an effective method to improve gas extraction efficiency, the enhanced gas extraction technology through gas injectio...
