Characterization and Controlling Factors of CBM Reservoirs,ores can be divided into macropores (>1000 nm), mesopores (100 to 1000 nm), small pores (10 to 100 nm) and micropores (<10 nm). Gas penetrates by laminar flow and turbulent flow in the macropores, and exists by means of capillary condensation, physical adsorption and diffusion in the micropores.

Coal Absorption Characteristics and Model Under Reservoir Conditions,orphic 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

Stimulation Mechanism and Application,ity. In the design of fracture height and width, it is necessary to have an accurate understanding of in-situ stress and coal rock mechanics. In addition, in the study of fracture pressure and wellbore stability in fracturing construction, it is also necessary to test and study the rock mechanical p
