| 摘 要： | 研究海底含蜡原油管道的停输降温过程,对避免＂凝管＂事故的发生起着重要的作用。针对海底含蜡原油管道运行环境的特点,建立海底管道停输时的非稳态传热模型,利用CFD软件模拟海底管道停输过程中温度随时间的变化规律,分析管径、管道周围海泥温度等因素对停输温降的影响,从而确定最佳停输时间,为海底含蜡原油管道制定再启动方案提供理论依据。

| Abstract: | In this paper,the temperature drop process of submarine waxy oil pipeline is researched.It is of great significance to avoid the accident of solidifing pipeline.According to the characteristics of service environments of submarine waxy oil pipeline,unsteady-state heat transfer model is established for submarine pipeline during shutdown.Regularity of change of waxy oil temperature is simulated in submarine pipeline during shutdown with time by the CFD software.The factors of effecting,such as diameter of pipeline and temperature of mud around the pipeline and so on,are analyzed,which decide a optimum time for shutdown and provides a theoretical guidance for safe submarine waxy oil pipeline startup. |
