Study on the pore evolution law of anthracite coal under liquid nitrogen freeze‐thaw cycles based on infrared thermal imaging and nuclear magnetic resonance
Abstract The waterless fracturing method with liquid nitrogen (LN2) as the fracturing fluid has been proposed and successfully applied in coalbed methane (CBM) production in recent years. The temperature of the coal reservoir sharply decreases, causing damage to the pore structure of the coal reserv...
