Abstract
The thermal conditions for buried oil pipelines were evaluated.The physical model and mathematical model for buried oil pipelines were established.Computational fluid dynamics software has worked out a numerical calculation method for buried stealing pipeline.The temperature field of buried oil pipeline was quite obvious in the ground region,and the temperature of buried oil pipeline is obviously high in the ground track region.An infrared image localization experiment plan of buried oil pipeline is made,experimental tests conducted,proving that the temperature field distribution in ground heat-affected zone of the oil pipeline is not very even.The simulation computation and the experimental study contrast indicated that the ground region temperature field of buried oil pipeline tallies both the simulation situation and the actual situation.
