When it is transferred the high-pour-point and viscous crude oil, heat loss was serious. And the heat loss was more serious after fault shutdown. When the shutdown time is beyond the safe shutdown time accident occurs. It is important to study the heat calculation of crude oil. Compared the winter and summer shutdown temperature drop of the crude oil. Different shutdown time was given, simulated the temperature drop of each time. Calculated the out-station temperature of shutdown crude oil. Simulated the threedimensional temperature field of soil and pipeline after the shutdown. Concluded that the change rules of crude oil and the soil temperature field at different temperature. When the outstation temperature reach a certain temperature, it can ensure shutdown and restart safety. The result provided a reference for the safety production.
