Analysis of Occurrence of Deep Coalbed Methane and Its “Desorption–Diffusion–Seepage” Process

Separations
China has abundant deep coalbed methane (CBM) resources; however, high temperature, stress, and reservoir pressure complicate the gas adsorption–desorption–diffusion–seepage processes, severely restricting the development of deep CBM. Through experimental research on adsorption, desorption, diffusion, and seepage behaviors of various coal samples, the ...
