非掩埋海底管道应用多波束系统双探头检测方法研究
|
摘要
以胜利油田海底管道为检测对象,采用双探头多波束系统对非掩埋海底管道进行了检测。检测实验结果证明扫测区波束密度加大,边缘波束质量得到明显提高,扫测盲点及盲区明显较少,能够较准确地反映管道的状态。同时双探头多波束系统降低了对测线的布设要求,减少了工作量,提高了检测效率。实验证明不同波束开角对双探头多波束系统检测结果影响不明显。
The submarine pipeline of Shengli Oilfield is taken as the object of detection,and a double probe multi-beam system is used to detect the non-buried submarine pipeline. The experimental results show that the beam density in the scanning area is increased,the quality of the edge beam is obviously improved,and the blind spots and blind areas are obviously fewer,which can reflect the state of the pipeline more accurately.At the same time,the dual-probe multi-beam system reduces the requirement of line layout,reduces the workload and improves the detection efficiency. Experiments show that different beam opening angles have no obvious influence on the detection results of dual-probe multi-beam system.
