| 摘 要： | 在国内首次对长输管线小泄漏直升机巡检效果进行试验验证.采用软件模拟和试验验证的方法确定小泄漏发生后的扩散范围,由直升机携带激光检测设备,对平原和山区的人工小泄漏源产生的甲烷气团进行检测.平地试验飞行高度为60～150 m,山区试验选择西气东输管线沿线具有代表性的地形作为5个人工泄漏源的放置地点,直升机在这些点的飞行高度为60～500 m.试验结果表明:直升机巡检方法适用于平原、沙漠、戈壁等地区,对地形起伏较大的丘陵、山地等地区效果不够理想.

| Abstract: | The effectiveness of airborne laser detection equipment on buried pipeline small leakage was firstly validated by experiment. Dispersion range of pipeline small leakage was simulated by software and verified by experiment. The methane clouds produced by artificial leakage sources,which are placed at plain and hill,are detected by the equipment on helicopter. The flight height is 60-150 m at plain. Five artificial leakage sources are placed along the West-East Pipeline at hill where flight height is 60-500 m... |
