Abstract
Under reservoir conditions, CBM is mainly absorbed on the pore surface of coal. The capacity of CBM storage is mainly related to factors such as metamorphic environment, composition, ash yield, moisture, reservoir pressure and temperature. Under similar metamorphism and sedimentary conditions, coal rock composition, ash yield, moisture and pore surface area are different, which can be reflected by isothermal absorption experiments on coal samples. After thermal evolution, coal seams with same metamorphism may be different in burial depth due to late structural deformation, so that the reservoir pressure and temperature change greatly.
