The liquid CO2 fracturing test and hydraulic fracturing test were conducted on tight sandstone. Three methods, CT scanning, 3D fracture morphology scanning and nuclear magnetic resonance measurement, were used to identify the pore and crack characteristics of the fracture samples from the micro to the macro. Fracturing stress time, nuclear magnetic resonance T2 spectrum and CT scanning crack initiation data are mainly recorded.\n</code></pre>",
