摘要
比较了储气库集输管道和长输管道的运行特点。对专家评分法进行了改进,制定了适用于集输管道的风险评分体系。以西气东输二线东段某储气库单井管道为例,利用改进后的风险评分法对其进行了评分,提出了缓解风险的措施。改进后的风险评分法适用于油田、储气库、炼化厂的拟建、在建和在役的集输管线初步风险评价,可达到识别管道沿线高风险后果区域、风险预警、策划事故应急方案及指导管道运营、改建、维护等安全管理工作。
This paper compared the running characteristics between the gathering pipeline of gas storage and long-distance pipeline,made improvement to expert evaluation method,worked out a suitable risk evaluation system.It took the case of single well pipeline in east section of the Second West to East Gas Pipeline,utilized the improved risk evaluation system to score,and put forward some measures to ease risks.The results showed that this improved risk EST applied to the initial risk evaluation of gathering pipeline which is planned construction,under construction and in service in oil field,gas storage and refining and chemical factories,it can identify high risk areas along pipeline,pre-warning,planning accident emergent program,and provide guidance to safety management,such as pipeline running,modification and maintenance.
