摘　　要：输油管道泄漏监测系统在成品油及原油管道运行中得到广泛应用,已经成为输油管道重要的保护措施。泄漏监测系统的性能指标受管道设计参数、工艺操作、测量误差等多种因素的影响,并且不同的运行工况下性能也不相同,性能指标尚没有统一的测评方法。为了提高泄漏监测系统的使用效果,从泄漏监测系统的监测灵敏度、定位精度、误报率、漏报率和管理制度等几个方面进行了影响因素分析,实现对泄漏监测系统使用效果的综合评价。通过实例分析不同工况条件下泄漏监测系统的实际性能指标,验证了理论分析的正确性,并有针对性地提出了技术改进措施。The leakage monitoring system of oil transportation pipeline has been widely used in the operation of product oil and crude oil pipelines,and become an important measure for pipeline protection.Many factors can affect performance indexes of the leakage monitoring system,such as pipeline design parameters,process operation,and measuring errors.And the performance under different working conditions is different,so there are no uniform standards to test and evaluate performance indexes.To improve the performance of the leakage monitoring system,influencing factors are analyzed from aspects such as sensitivity,positioning accuracy,false alarm rate,missed alarm rate,and management system,realizing the comprehensive evaluation of the leakage monitoring system.Instances are used to analyze the actual measurement performances under different working conditions,correctness of theory analysis is proved,and pointed technological improvement measures are put forward.
