Reservoir rock hole crack three-dimensional visualization and gas flow simulation method

The invention discloses a reservoir rock pore fracture three-dimensional visualization and gas flow simulation method, which comprises the following steps: carrying out three-dimensional CT scanning on a rock sample in a non-stress state to obtain rock sample model data, and carrying out 3D printing on a rock sample model by processing the scanned data and a 3D printing technology; carrying out mechanical seepage physical experiments and real-time CT scanning on the rock sample and the rock sample model in a stress state respectively, and carrying out seepage numerical simulation on the basisof establishing a 3D digital model; analyzing the difference between the result of the mechanical seepage physical experiment and the result of gas seepage numerical simulation after real-time CT scanning, and deducing the most suitable gas flow equation in numerical simulation software through the result of the mechanical seepage physical experiment. The method has the beneficial effects that theapplication range is wide
