| 摘 要： | 对国内某WK掺稀稠油保温管道，进行工艺特性分析和安全输送能力计算。结果表明：①加热输送的掺稀稠油管道存在随输量减小压降急剧增大的不稳定区；②掺稀比增大时，管道的不稳定工作区左移，安全输送的临界输量减小，有利于管道在低输量下安全运行；③最大输送能力并非随掺稀比或首站出站油温单调递增；在某一掺稀比和/或首站出站油温下，WK掺稀稠油管道具有最大输送能力；④WK线的整体压降受掺稀比、输量的影响较大，但季节对压降的影响很小；⑤WK线整体温降主要受输量影响，而掺稀比、季节对其影响不大；⑥对于同一种掺稀比稠油和同样的出站温度，在不同季节下的末站进站温度、临界输量以及最大输送能力相近。

| Abstract: | This paper investigated the thermo-hydraulic characteristics of diluted heavy crude insulated WK pipeline，and calculated the safe flow rate ranges. Results showed：①Unsteady working zones，which demonstrate sharp increases in pressure losses with decreased flow rates，occurred to the hot diluted heavy crude pipeline. ②With increasing dilution ratios，the unsteady zones moved to smaller flow rates，and hence safe working zones of the pipeline were enlarged. ③The maximum throughputs of WK pipeline did not increase monotonously with dilution ratios or/and its inlet temperatures，and its maximum pipelining capacities took place at certain dilution ratios and inlet temperatures. ④The total pressure drops of WK pipeline were considerably affected by dilution ratios and flow rates，but not by seasons. ⑤Flow rates had significant impacts on the total temperature drops of WK pipeline，but dilution ratios and seasons did not have such impacts. ⑥With regard to the same dilution ratios and inlet temperatures，the outlet temperatures，critical flow rates and the maximum throughputs of the pipeline differed little in different seasons. |
