Abstract: In view of the problem of different oil pipelines leakage, using the finite volume method to build the three dimensional flow and mass transfer mathematical model of the soil porous media around underground pipeline, by the CFD soft to numerical simulate the range of different oil distribution of underground and the earth’s surface when petrol, diesel fuel or crude oil pipeline leakage, the simulation results showed that when the time was the same, the volume of diesel fuel leakage was the most, and the spread was more 20% than petrol or crude oil. After 2 hours’ leakage, the diffusion rates of both underground and surface cases tended to be stable. The simulation diffusion scopes of leakage oil had a guiding significance for repair work of contaminated soil.
