Abstract:Sandstone is a common type of rock found in coal measure reservoirs, and its pore and fracture distributions are key factors influencing the comining of coal and gas. To improve the structure of coal measure reservoirs and enhance interlayer compatibility, a method for high-and low-temperature cyclic impact on sandstone was developed in this study, and the effects of high-temperature (+200 °C) and low-temperature (−196 °C) cyclic impacts (number of cycles: 0, 1, 5, 10, and 15) on the pore and fracture distribu… Show more
