建立电伴热方式的稠油伴热管道二维非稳态模型，分析了管道的保温层厚度、伴热管个数以及位置参数对稠油管道安全停输时间的影响及其变化规律。研究结果表明，在单管伴热的情况下，管道的保温层厚度分别为60、70 mm和80 mm时，安全停输时间分别为26、30 h和34 h；在双管伴热的情况下，双管夹角的变化对安全停输时间的影响较小，安全停输时间约为36 h。

The heavy oil electric heat pipe tracing two-dimensional unsteady model was established to analyze the influence and the laws of heavy oil pipeline safety shutdown time under the thickness of pipe insulation,the number of heating pipes and location parameters.The results show that in the case of a single tube with heat,when the pipe thickness was respectively 60, 70 mm,and 80 mm,corresponding security shutdown time was about 26,30 h,and 34 h;in the case of double pipes heating, the change of the angle between the two tubes had the smaller impact on the safety shutdown time,and the safety shutdown time was about 3 6 h.
