成品油管道运行过程中的漏油现象是不可避免的。如管道腐蚀穿孔；外力作用造成管道破裂；进站处跑油等。准确确定漏油点、计算最大漏油量以及漏油后全线工况变化分析，是保证成品油管道及时检修处理、安全合理输送必须进行的工作。本文就上述三个问题进行研究探讨，得到较满意的分析方法和计算方法。 Oil spill during operation of the product pipeline is inevitable. Such as pipeline corrosion perforation; external force caused by pipeline rupture; pit stop running oil. Accurately determine the oil spill point to calculate the maximum amount of oil leakage and changes in the entire line after the leak analysis is to ensure that the timely repair oil products pipeline handling, safe and reasonable delivery must be carried out. In this paper, the above three issues are studied and discussed, and the satisfactory analytical methods and calculation methods are obtained.
