浅海底瞬变电磁探测技术研究新进展

瞬变电磁法应用于浅海底进行资源勘探或工程地质勘查时,需要将仪器系统和观测装置置于海底,以克服海水屏蔽效应。因此,要求能够远程控制仪器进行自动化数据采集;同时,受工作环境影响,需要将观测装置小型化;另外,通过拖曳式测量提高工作效率。总结课题组目前的研究成果,就仪器系统研制、观测装置小型化、拖曳式测量及海水影响等内容的研究进展进行了简要叙述。

Researching Progress of Shallow Seafloor Exploration Using Transient Electromagnetic Systems

When transient electromagnetic system is applied to sea-floor resource exploration and engineering geology investigation,the instrument systems and arrangements need to be put into the seawater to avoid the shield of conductive seawater.So it is necessary to realize auto-acquisition by telecontrol,and miniaturize the arrangement because of the confine of working conditions.In addition,towing measurement can get higher work efficiency.By summarizing the studying production on shallow seafloor transient electromagnetic exploration of our study group,this article introduces the progress of the instrument-development,arrangement-miniaturization,tow-measure and seawater-effect study briefly.
