海底管道泄漏检测研究进展

Research Progress in the Leakage Detection Technology for Submarine Pipelines

随着海洋石油技术的发展,穿越海底的油气管道数量不断增多,海底管道泄漏的危险也随之增加。因此,对海底管道泄漏的检测显得愈发的重要,但多数陆上埋地管道泄漏的检测方法不适用于海底管道。将海底管道的常用的和新兴的检测技术归纳为以下四类检测方法,即直接检测、管内流动运行设备检测、管壁系缆式检测和管外设备间接检测。并对这些方法所包括的技术进行了分析、比较,提出今后的研究方向及重点,以期为进一步的研究提供参考。

With the development of the offshore oil technology, the number of oil and gas pipeline through the seabed continuously increases, at the same time the risk of submarine pipeline leakage also increases. So, the detection of subsea pipeline leak is becoming increasingly important. But the onshore pipeline leak detection method doesn’t apply to submarine pipelines. In this paper, common and new detection technologies for submarine pipelines were categorized into four kinds： direct detection method, pipeline internal flowing equipment detection method, pipeline wall moored detection method and pipeline external equipment indirect detection method. And these technologies were analyzed and compared; their research direction and emphasis in future were proposed, which could provide the reference for further research.
