摘　　要：为研究海底热油管道的停输温降,建立海底热油管道传热计算的二维简化模型,通过结构化网格细化"钢管-保温层-钢管"3层结构,得到在正常工况下海底热油管道周围的海泥温度场,并以此为基础研究海底热油管道停输温降的影响因素,对海底热油管道的设计和生产管理有一定的指导意义。In order to further study the temperature drop of the buried hot submarine oil pipeline during shutdown,a simplified two-dimensional heat transfer model is built,and a structured grid is applied to generate grids for the three layers"steel,insulation and steel"in the pipe.The temperature drop characteristics of the buried hot submarine oil pipeline during shutdown is obtained on the hase of sea mud temperature field under normal condition.The influence factors of the temperature drop of the buried hot submarine oil pipeline during shut-down are obtained,It provides reference for design and operation management.
