Abstract

Abstract:

The soil section model of cold and hot oil pipelines was established and the CFD software was used to simulate the variation of soil temperature field in summer and winter and soil temperature field reconstruction. The results showed that the hot oil temperature field was destroyed after 120 h after changing to transport cold oil in winter. In summer, the process was slow due to the ground temperature high and the temperature field could not be completely destroyed. When the accumulation of heat was destroyed in winter, the temperature of the hot oil need be raised to ensure the safety of transporting. Taking the example of Changchun to Jilin pipeline in winter, the accumulation of soil heat was completely destroyed after transporting 240 h cold oil .When it was changed to hot oil, the out-station temperature would be increased to 53 ℃ and transport 30 h, which could return to previously stable oil temperature field. In actual, the results could be used as a reference to ensure the transportation safety.

摘要： 建立冷热油输送管道的土壤截面模型,利用CFD软件模拟夏冬季节冷热原油交替输送土壤温度场的变化情况,以及再次改输热油时温度场的重建情况。模拟结果表明,冬季改输冷油后热油管道形成的温度场120h基本被破坏;夏季改输冷油后热量消耗缓慢,由于地温较高,可继续对冷油放热,温度场不能完全被破坏。当冬季土壤温度场被破坏,再次输送热油时,需要提高热油温度,以保证输送安全。以长吉输油管线冬季情况为例,输冷油240h后土壤温度场完全被破坏,再次输送热油时,将出站热油提高到53℃,输送30h后,即可以恢复到先前的稳定热油温度场。在实际输送过程中,可以把交替输送中的温度场变化作为确保输送安全的参考依据之一。
