摘要:  通过对保温原油实验环道的传热分析,建立保温含蜡原油实验环道温度场计算模型,计算得到管道内部温度分布,以及管道内壁温度梯度变化规律。对不同环境温度、油流速度和有无结蜡对管道温度场分布的影响规律进行分析。结果表明,管内油温与套管中的冷却水温差越大,管壁的平均温度梯度越大;管壁的平均温度梯度随油流速度增加而增大;当管壁上有了沉积物,沉积层内表面的温度梯度比初始时刻有所降低,降幅随着距离入口端长度的增加逐步减小。

Abstract: Through the heat transfer analysis of the experimental loop of the insulated crude oil, the calculation model of the experimental loop temperature field of the insulated waxy crude oil was established.The internal temperature distribution of the pipeline and the variation of the temperature gradient of the inner wall of the pipeline were calculated.The effects of different ambient temperature,oil flow velocity and wax formation on the temperature field distribution of the pipeline were studied.The results showed that the greater the temperature difference between the oil temperature in the tube and the cooling water in the casing,the larger the average temperature gradient of the tube wall.The average temperature gradient of the pipe wall increased as the oil flow velocity increased,however,when the temperature gradient of the inner surface of the sediment deposit layer on the pipe wall was lower than the initial time, the magnitude of the decrease gradually decreased as the length from the inlet end increased.

Key words: Insulation crude oil pipeline, Temperature field distribution, Wax deposition, Numerical calculation
