Study on Temperature Field Reconstruction of Cold and Hot Crude Oil T ransportation
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 .
