摘要
近年来,油田打孔盗油、腐蚀穿孔等输油管道泄漏事故频繁发生,由此带来了经济损失及环境污染的严重后果,为此进行了输油管道的在线监测系统研究。研制的G300管道泄漏监测报警定位系统采用自适应滤波算法和现代数字信号处理技术、模式识别算法,极大地提高了定位精度,降低了漏报率和误报率。可针对所监测管段全天候实时监测,对管道运行中发生的泄漏等异常事件进行报警、定位。与GPS为核心的定位导航系统及精确的管道电子地图相结合,可及时准确找到泄漏现场,使管道泄漏损失降到最低。试验结果表明:最小泄漏孔径为3 mm,泄漏点平均定位精度小于10 m,泄漏报警时间小于15 s,没有出现漏报情况。研制的系统可为油田输油管道的在线监测提供技术支撑。
In recent years,oil pipeline leakage accidents resulted from perforating to steal oil and corrosion perforation have occurred frequently in oilfields,resulting in serious economic losses and environmental pollution.Therefore,an on-line monitoring system for oil pipeline was studied.The G300 pipeline leakage monitoring and alarm positioning system developed in the paper adopts adaptive filtering algorithm,modern digital signal processing technology and pattern recognition algorithm,greatly improving positioning accuracy and reducing missed and false alarm rates.The system can monitor the monitored pipeline section in real time and any kind of weather,and provide alarms and location for abnormal events such as leaks that occur during pipeline operation.Combined with positioning and navigation system that takes GPS as the core and precise pipeline electronic map,the system can timely and accurately locate the leakage site,minimizing pipeline leakage losses.The test results show that the minimum leakage aperture is 3 mm,the average positioning accuracy of the leakage point is less than 10 m,the leakage alarm time is less than 15 s,and there are no missed reports.The developed system provides technical support for on-line monitoring of oil pipelines of oilfields.
