Influence of gas migration on permeability of soft coalbed methane reservoirs under true triaxial stress conditions

The permeability of the coal body is the key parameter restricting the efficient extraction of coalbed methane, and scholars have analysed it from two angles of the change of stress state and porosity of the coal body. However, there is still a lack of study on the mechanism of gas migration and mov...
