The governing equations of the diffusion of the gas were presented based on the diffusion process of sour natural gas after the perforation leakage of the buried pipeline. Numerical simulation of the leaking process of the gas under different conditions was discussed, and the diffusion laws of hydrogen sulfide and methane were obtained. A systematic study on the difference of the diffusion laws was carried out, which could provide theoretical basis for the further study on the diffusion law of leaked hazardous gas.
