Experimental study on the coupling effect of pore-fracture system and permeability controlled by stress in high-rank coal

During the coalbed methane (CBM) exploitation, the reservoir permeability can be affected by the effective stress that varies with the reservoir fluid pressure, which is a complex, dynamic and significant engineering problem. To analyze the response characteristics of the pore-fracture system by the...
