摘　　要：某海底原油管道设置了负压波泄漏检测系统,但该系统误报漏报情况非常严重,无法实现有效的泄漏检测报警功能。根据负压波泄漏检测的基本原理,结合现场仪表的安装设置情况及管道的实际运行工况,具体分析了负压波泄漏检测系统失效的主要原因。根据现场情况,提出了采用次声波泄漏检测系统的解决方案,介绍了次声波泄漏检测系统的组成及技术参数。经过放油试验,证明该系统可以有效地实现泄漏的报警和定位。A negative pressure wave leak detection system in submarine crude oil pipelines often fails because of very high false positives and false negatives. According to the basic principle of negative pressure wave leak detection, the major reasons of failure are analyzed, based on the instruments mounting situation and the real operational condition of the submarine pipeline. The solution of infrasonic wave leak detection is presented in light of the site situation. The technical paramenters and system composi- tion of the infrasonic wave leak detection system are introduced. The system can give leakage alarm and indicate the position suc- cessfully in the proecess of oil drainage tests.
