The thermal process in the preheating of pipelines was simulated with crude oil parameters, and the corresponding thermodynamic calculation model was established. And finite volume method was utilized to simulate preheating process of a China's Northeast crude oil pipeline which transports Daqing oil, and the soil heat storage capacity was calculated. At last the change rule of soil temperature field in the preheating process was described.
