摘　　要：针对东北管网埋地热油管道输油工况、管道及其周围土壤热力参数变化频繁的问题,设计了一套可以测定管道沿线不同位置的管壁温度和土壤温度场的装置。利用该装置中分布在不同位置的铂电阻测温仪可以获得土壤截面5个方向上与管壁距离不同的43处温度。应用该套装置测定了东北管网部分管道在正常运行、停输再启动、开挖大修等工况下沿线不同截面管壁和土壤的温度分布,并参照实际生产数据进行分析。结果表明该测定装置可以准确地检测到管壁和管道截面土壤的温度,能够反映不同工况下管道及其周围土壤的热力变化规律,为热油管道的安全运行提供技术支持。An apparatus to measure pipe wall temperature and soil temperature field at different locations along pipeline is developed in the light of the problems existed in operating condition,pipeline and thermal parameters of soil around pipeline being frequently changed in buried hot oil pipeline of Northeast Oil Pipeline networks.platinum resistor thermodetectors distributed in different positions are used to obtain temperatures at 43 positions in 5 directions of soil cross section with different pipe wall distances.The apparatus is adopted to measure the temperature distribution of different cross section pipe wall and soil along pipeline under the condition of normal operation,shut-down and startup,opening for overhaul,etc.for partial pipeline in the pipeline networks,and analysis is made referencing actual operating data.Result shows that this apparatus can accurately detect the temperatures of pipe wall and soil of pipe cross section,and can reflect the law of thermal variation of pipeline and soil around pipeline at different operating conditions,which provide technical support for safety operation of hot oil pipeline.
