摘要
论文概述了海洋资源电磁勘探发展状况,介绍了极低频探地工程组成,论述了极低频信号随距离传播特性,计算极低频穿透海水深度;通过实际试验进行了初步验证,证明极低频探地工程覆盖范围大,覆盖我国领土和近海,并总结归纳了极低频探地工程应用于海洋资源的特点。极低频探地工程为我国海洋石油矿产等资源的勘探开发提供了一种新手段,将推动我国海洋电磁勘探技术的发展。
In this paper,the development of electromagnetic exploration in marine resources is described,and the composition of wireless electro-magnetic method(WEM)and characteristics of WEM signal propagation with distance are introduced.Then the seawater penetration depth of WEM signals is calculated and proved by actual tests.It is proven that WEM signal covers a wide range of China’s territory as well as offshore areas,and the features of application of WEM project to marine resources are summarized.WEM project provides a new method for detection of China’soil and mineral marine resources,and promotes the development of China’s marine electromagnetic exploration technology.
