Abstract
As an environmentally waterless fracturing technology, supercritical carbon dioxide (SC-CO2) fracturing technology is gaining more and more attention in the process of safe mining of coal resources. Based on the phase change of CO2 in the fracturing process, a staged numerical simulation method of SC-CO2 fracturing considering the change of CO2 phase was proposed, and the fluid-solid coupling numerical model of adjacent fracturing boreholes in...
