靖—咸原油管线泄漏报警检测系统试验研究

靖安—咸阳输油管道全长463km，沿线设有6个泵站，用SCADA系统进行监控、管理，用北京中加诚信管道公司基于负压波原理编制的PIPELEAK3.1软件对管道沿线的泄漏进行报警监测。为了验证检漏系统的适用性，分别在靖安—王窑段、杨山—洛川段和耀县—咸阳段三个管段上选择阀室进行泄放模拟试验，试验结果表明：当管线处于满流工况时，该检漏系统能够及时准确的定位，并能计算出泄漏量。由于管线处于满流工况对生产存在不利，偷盗油事故的存在使得该系统的适用性存在一定的限制，因此调度人员应根据生产实际情况结合该系统并引入辅助检测手段对管段作出详细分析，发挥该检漏系统应有的作用。

THE EXPERIMENT OF LEAKAGE MONITORING SYSTEM OF JING-XIAN OIL PIPE

The Jing′an-Xianyang pipeline is 463km long with 6 pump stations and monitored and managed with SCADA system. PIPELEAK3.1 software, which is written based on the priciple of negtive pressure wave by Beijing SinoCanadian Cheng-xin Pipeline Co, is used there for warning and monitoring pipe leaking. Valve stations in three pipe segments are choosed for leaking experiment to validate the applicability of PIPELEAK3.1 software at Jing′an-Wangyao section, Yangshan-Luochuan section and Yaoxianxianyang section. The experiment result shows that the system can have timely and accurate orientation and calculate the leaking amount when pipe is full of fluid. However, the actual condition is complicated because of the disbennifit caused by the full fluid condition and application distraction caused by oil stealing. Therefore, operators should make particular analysis based on actual condition and combine with other monitoring ways to put the system in good use.
