摘　　要：目前秦京输油管道处在接近于生产规程规定的最低输量状态下运行,流动安全性问题值得关注。针对缺少定量评价结果的情况,利用原油管道停输再启动凝管概率计算软件,评价了秦京输油管道在当前输量和生产规程规定的允许停输时间下停输再启动的安全性,并提出在不同站间合理分配安全裕量的建议,探讨了基于流动安全性评价结果,分站间进行工艺参数优化配置的可行性。秦京输油管道全线大部分站场在全年大多数月份安全性良好,可以考虑通过降低进站温度或延长允许停输时间等方法合理分配安全裕量,为秦京输油管道在保障流动安全性的前提下实现经济输送提供保证。Qinhuangdao-Beijing Oil Pipeline is closely running at the minimum specified throughput,and its flow safety issue is of great concern. In the light of lacking of quantitative evaluation results,the safety evaluation of shutdown and restart for Qinhuangdao-Beijing Oil Pipeline operated under the conditions of current throughput and the allowable shutdown time is carried out by means of the crude oil pipeline shutdown and restart congelation probability calculation software,and the suggestion on reasonably distributing safety margin between stations is put forward. Besides,the flow safety evaluation results and the feasibility in optimizing process parameters between stations are discussed. The safety for most of the stations in Qinhuangdao-Beijing Oil Pipeline are satisfactory from most of months to the year,and the reasonable allocation of safety margin can be made by reducing the inlet temperature or extending the shutdown time and other methods. The results can provide a guaranty to the economic transportation for Qinhuangdao-Beijing Oil Pipeline under the precondition of flow safety.
