海洋水下管线综合探测方法应用研究

Research on Application of Underwater Pipeline Detection Method

海洋水下管线探测是海洋开发建设的基础工作,海洋物探是海洋水下管线探测的主要方法。为了完成某海域水下管线探测,本文提出了磁法探测与侧扫声呐和浅地层剖面探测相结合的综合探测法,该方法先采用磁法探测对整个测区进行全面扫测,建立海洋磁场分布图,然后采用侧扫声呐和浅地层剖面探测技术对磁力异常值区域进行二次探测,查明磁力异常原因,判断管线分布情况。以某海域为例进行实验分析,结果表明:综合探测法具有较好的探测效果,侧扫声呐技术能够探测到微小的铁磁性物体。

Marine underwater pipeline detection is the basic work of ocean development and construction,and marine geophysical prospecting is the main method of marine underwater pipeline detection.In order to complete the underwater pipeline detection in a certain sea area,this paper proposes a comprehensive detection method combining magnetic detection,side scan sonar and shallow formation profile detection.Magnetic field distribution map,and then use side scan sonar and shallow formation profile detection technology to conduct secondary detection of the magnetic anomaly area to find out the cause of the magnetic anomaly and determine the distribution of pipelines.Taking a certain sea area as an example,the experimental analysis shows that the comprehensive detection method has a good detection effect,and the side scan sonar technology can detect tiny ferromagnetic objects.
