Evolution of Pore–Fracture Structure in Deep Coal During CO2 Energy Storage Fracturing
CO2 fracturing is an important stimulation method for deep coal seams, but the relationships among coal structural changes during CO2 exposure, pressure response, and post-fracturing network development require further characterization. High-temperature, high-pressure CO2 soaking, pore structure and mechanical tests, e...
