摘　　要：梳理了我国含蜡原油停输温降的最新研究进展,强调了停输过程中析蜡潜热对原油温度场的影响以及合理处理凝固潜热的必要性;在传热学的理论基础之上,研究了用显热容法建立的新的数学模型。热油管道停输温降过程是输油管道中常见的现象,研究含蜡原油管道停输过程的温度变化规律,为原油输送管道的科学设计和安全、经济运行提供了一定的理论参考。New research progress in shutdown temperature crop of buried wax oil pipelines in China was introduced. Influence of latent heat of wax precipitation during the shutdown on crude oil temperature field was discussed as well as the necessity of dealing with solidification latent heat. Based on the heat transfer theory, a new mathematical model was established with the method of apparent heat capacity. The temperature drop of hot oil pipelines is a common phenomenon in oil pipelines, research on the temperature variation of wax oil pipelines will provide some theoretical references for scientific design and economic-safe running of oil pipelines.
