摘　　要：并行埋地管道中,常温输送的成品油管道会影响热原油管道的温度场,从而与单根输油管道的温度场不同。热油管道周围土壤温度场是管道停输再启动和管道运行的基础,只有准确掌握管道周围土壤温度场的变化规律,才能使管道安全运行,避免凝管事故发生。为了研究并行管道周围土壤温度场在准周期内的变化规律,以西部原油成品油管道四堡进站位置为例,在实测管道周围土壤物性的基础上,采用非结构化有限容积法对并行埋地管道周围土壤温度场进行模拟研究。模拟计算结果与现场实测结果基本吻合,表明提出的计算模型正确,计算结果能够为工程实际提供参考。In the area of parallel buried pipelines,a temperature field of hot crude oil pipelines is influenced by the cool processed oil pipelines,therefore the temperature field of parallel pipelines is different from that of single pipeline.For hot crude oil pipeline,the soil temperature of hot crude oil pipeline is the base of shut down,start-up,and operation.It is necessary to acquaint the soil temperature in order to make sure the pipeline operate safely and avoid the pipeline condenser.Based on the soil properties measurement,the finite volume method is adopted to research the quasi-periodic soil temperature field around parallel buried pipelines by using quasi-periodic soil temperature field of parallel buried pipelines at Sipu inlet station of west pipeline as the example.The simulating data conform with the measured data,it is indicated that the mathematical model is correct and the results provide the reference for the engineering.
