快速、准确地识别出油气管道高后果区,对降低管道沿线人员伤亡、财产损失以及环境破坏具有重要作用。当前油气管道高后果区识别工作存在任务重、效率低、识别准确率低等问题。为了更好地开展油气管道高后果区识别工作,梳理了国内外油气管道高后果区识别的技术现状、高后果区的主要类型及识别规则,提出了一种基于GIS缓冲区分析的油气管道高后果区识别方法,并利用该方法对某地区输油管道进行高后果区识别实践,快速识别出该地区输油管线的高后果区地段。结果证明，该方法具有效率高,节省人力、财力和物力的优势，为油气管道高后果区识别工作提供了方法借鉴。

 Quickly and accurately identifying the high consequences areas of oil and gas pipelines plays an important role in reducing casualties, property losses and environmental damage along the pipeline. At present, the identification of high consequence areas of oil and gas pipelines has some issues, such as heavy task, low efficiency and low accuracy. This paper collects the technical status of high consequence areas identification of oil and gas pipeline at home and abroad, the main types and identification rules of high consequence areas, and proposes a method for identifying high consequence areas of oil and gas pipelines based on GIS buffer analysis. The high consequence areas identification practice using this method is carried out on the oil pipelines in a certain area, which quickly identifies the high consequence areas of oil pipeline in the region. It is proved that this method has the advantages of high efficiency and manpower, financial and material resources saving, which provides reference for the oil & gas pipeline high consequence areas identification.
