摘　　要：为了更加准确地确定冷热原油顺序输送温度场波动规律,对管道周围土壤温度场绝热面漂移进行了研究。针对冷热原油顺序输送过程中埋地管道周围土壤温度场变化特征,建立了土壤温度场非稳态传热模型,利用CFD软件,对冷热原油顺序输送过程中不同循环周期不同时刻的土壤温度场进行了数值模拟及分析。结果表明,土壤温度场绝热面的漂移具有一定的规律,绝热面随冷热原油顺序输送时间呈周期性漂移,漂移周期与冷热油顺序输送的循环周期相同;土壤温度场绝热面的漂移周期及距离与冷热油顺序输送的循环周期有关。In order to more accurately determine the crude oil batching transportation temperature fluctuation, the soil temperature field around pipeline insulation surface drift was studied. For variation characteristics of soil temperature field around underground pipeline in the process of batching transportation of cold and hot crude oil, the non steady heat transfer model was established, and soil temperature field in different period of hatching cycles and moments was numerically simulated and analyzed by using CFD software in the process of crude oil batching transportation. The results show that the drift on the thermal insulation surface of soil temperature field has certain regularity, and adiabatic surface with crude oil hatching transportation time shows periodic drift, drift period and period of batching cycles of cold and hot oil transportation were the same; drift cycle of thermal insulation surface of soil temperature field and the scope are related to cold and hot cycle on the batch transportation of oil.
