基于声波探测的海底管道非掩埋状态检测方法

Integrated acoustic survey method for inspecting the unburied status of submarine pipeline

基于声波探测技术,提出一种对海底管道非掩埋状态进行联合检测的方法,以山东胜利油田某海底输油管道为对象,设计一种双声纳探头多波束测深系统,并联合侧扫声纳系统,通过对系统参数进行分析、优化,从而实现对海底管道非掩埋状态的高效精确检测。分析检测结果表明:基于双声纳探头多波束系统的海底管道检测可获得高密度的点云数据,显著提高了管道检测数据的稳定性及可靠性;侧扫声纳系统的良好检测效果有赖于其声波掠射角的最佳取值;参数优化后的联合检测系统的检测效率得到显著提高,能够精确判断出管道的实际状态。

Based on acoustic survey, an integrated method for inspecting the unburied status of submarine pipeline is proposed. A Multi-Beam Bathymetric System （MBS） with dual-sonar sensors and a side-scan sonar system is employed in this method, and analyzing and optimizing of system parameters are implemented for efficient and accurate inspection of the unburied status of submarine pipeline at Shengli Oil Field in Shandong Province. The analysis of inspection results shows that the MBS with dual sonar sensors is able to obtain high-density point cloud data of submarine pipeline, which greatly improves the stability and reliability of the inspecting data. The well inspecting effect of a side-scan sonar system is dependant on the optimum value of its acoustic grazing angle. With the help of the optimized system parameters, the detection efficiency of the integrated system is significantly improved so that the actual status of submarine pipe can be determined more precisely.
