摘要: 易凝高黏原油在加热输送过程中热量损耗严重, 遇故障停输后热量的散失更为迅速, 当所需停输的
时间超出安全停输时间时就会发生事故。因此, 研究原油的热力计算对管道的安全运行具有重要意义。对比了冬
夏两季原油停输温降的变化规律, 在停输时间不同的条件下, 对温降进行了数值模拟, 计算出原油停输前所需的出
站温度。对停输后的土壤和管道的温度场进行了三维数值模拟, 找出了出站温度不同时停输后原油和土壤温度场
的变化规律。在出站温度达到一定值后, 原油在所需的停输时间内可以保证安全再启动, 不会发生事故或造成安全
隐患。

Abstract:

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 threedimensional 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 outstation temperature reach a certain temperature, it can ensure shutdown and restart safety. The result provided a reference for the safety production.
