Study on the influencing factors of radial non-Darcy seepage of gas in CO2 fracturing boreholes

CO2 fracturing, as a key technology to improve the gas extraction efficiency of low-permeability coal seams, has a core mechanism of injecting high-pressure CO2 into coal seams to induce the generation of a fracture network within the coal body, thus greatly improving the permeability of the coal se...
