摘　　要：架空注汽管线保温材料沉降对评估管线散热损失、计算经济效益会产生显著影响。建立了保温材料沉降注汽管线周向传热模型,分析了环境风速、管线管径以及土壤辐射对管线热损失的影响。结果表明,增加风速导致偏心保温管线热损失增加,环境风速增加120%时,管线外保温热损失增加5.9%;在偏心率相同的情况下,管径越大,其空气夹层热损失越小;与不考虑土壤辐射相比,考虑土壤辐射时管线外壁面平均热流密度降低1 036W/m2。The settlement of thermal insulation materials for overhead heavy oil injection pipelines will have a significant impact on the assessment of pipeline heat loss and calculation of economic benefits.A heat transfer model of the heat⁃insulating material settlement steam injection pipeline was established,and the effects of environmental wind speed,pipeline diameter and soil radiation on pipeline heat loss were analyzed.The results show that increasing the outdoor environment wind speed leads to increased heat loss of the eccentric insulation pipe,and when the environmental wind speed increases by 120%,the heat loss outside the pipeline insulation increases by 5.9%.The larger the pipe diameter,the smaller the heat loss of the air interlayer.The average heat flux of the outer wall of the insulated eccentric insulation pipeline is reduced by 1036 W/m2 compared with the soil radiation.
