摘　　要：天然气长输管道是输气管道工程的基础工程设施,输气介质天然气属于易燃易爆物质,管道具有高压力属性主要风险为天然气的泄漏点火产生喷射火、闪火和蒸汽云爆炸。文章采用DNV Safeti软件对某输气管道高后果区进行了定量分析,计算出喷射火、闪火和蒸汽云爆炸的影响距离,以及计算出个人风险等值线和社会风险曲线,为建设项目设计、运行提供参考。可以为管道企业明确管道高后果区可能的影响范围和可能造成的后果,还可以企业在管道防腐管理、地灾管理、管道维修维护与保卫保护等方面采取针对性的的管理措施和技术措施,从而进行有效风险控制,减小管道沿线的环境影响和公众损失。Natural gas long-distance pipelines are the basic engineering facilities of gas pipeline engineering.The gas transmission medium,that is natural gas,is flammable and explosive substance.The high pressure property of pipeline is the main risks of jet fire,flash fire,and steam cloud explosion caused by natural gas leakage ignition.In this paper,the DNV Safeti software was used to quantitatively analyze the high consequence area of a gas pipeline.The impact distances of jet fire,flash fire,and steam cloud explosion as well as the personal risk contour and social risk curve were calculated.It could provid reference for the design and operation of construction projects.It could clarify the possible impact scope and consequences of high consequence areas for pipeline enterprises,and also take targeted management and technical measures in pipeline anti-corrosion management,disaster management,pipeline maintenance and security protection.Thus effective risks control was carried out to reduce the environment impact and public loss.
