The Analysis of Crude Oil Nature’s Impact on Oil Pipeline Underground Divulging Pollutant Migration

Abstract:

The oil pipeline burying divulging pollutant was taken as the object of study in this paper, the heat transfer and mass transfer process of which in the soil porous medium were carried by the numerical analysis. The oil phase change for multiphase flow leakage process for buried pipelines for oil, gas and water in the low temperature was considered, and the impact on multiphase leakage process of high and low viscosity of the oil phase viscosity properties was analyzed. It cited multiphase pipeline leak by using Fluent at different times during the course of the earth temperature field , the oil / water phase distribution , surface temperature, and the results showed that : there existed a big difference between the multiphase flow leakage process surface temperature changes and porous medium heat and mass transfer processes with the conditions of high viscosity and low viscosity conditions . Therefore, the impact of the physical properties on buried oil pipeline leak process at low temperatures is great.
