摘要:  对热油管道停输温降规律进行研究, 是确保管线安全启动的首要条件。针对海底热油管道运行环境特点, 基于多孔介质传热理论, 建立了海底土壤水热耦合控制方程, 用软件模拟了海底管道停输过程中温度随时间的变化规律, 分析了保温层、 渗流温度、 渗流速度等因素对管道停输温降的影响, 确定了合理的停输时间。研究结果可为海底管道安全启动提供理论指导。

Abstract: The research of shutdown temperature drop rule in heated oil pipeline was the primary condition to ensure the safe restarts of the pipeline. According to the characteristics of service environments of submarine oil pipeline, based on the theory of porous media heat transfer, the submarine soil moistureheat coupling equation was established. Regularity of change of oil temperature was simulated in submarine pipeline during shutdown with time by software.The factors of effecting,such as thermal insulation layer, temperature of seepage flow and speed of seepage flow and so on,were analyzed,which decided a rational time for shutdown and provided a theoretical guidance for safe submarine oil pipeline startup.

Key words: Seepage flow, Heated oil pipeline, Porous media, Shutdown, Numerical simulation
