浅海OBC地震勘探弯线施工导航质控方式优化研究

Study on the optimization of navigation quality control method for construction of curved line of offshore OBC seismic survey

本文针对国外某海洋地震勘探OBC项目,在复杂地形中为了规避相邻的自由弯线相交、减少船舶掉头上线次数的需求,提出了一种提高现场导航质控的解决方案:利用导航软件加载缓冲区底图辅助驾驶,施工过程中实时追踪船舶轨迹,下线后快速可视化检查成果SPS。通过野外应用表明,该方案使得导航人员能够更加直观、快速、准确、全面地进行现场质量控制(以下简称质控),保证了采集工作的有序进行。

This article focuses on how to avoid the intersection of adjacent curved lines and reduce the times of vessel to turn online in the complex work area of a foreign offshore seismic exploration OBC project,and studies a solution to improve site navigation quality control.Load buffer map in navigation software to assist driving,monitor vessel track in real time during the work,and quickly visually check the results of SPS after offline.Field using shows that the solution enables navigators can be more intuitive,fast,accurate,and fully conduct on-site quality control to ensure the orderly seismic work.
