摘要
电磁勘探是一项很重要的地球物理勘探方法。EH - 4是美国生产的新型电磁仪 ,它能精确的测量几米到 1 0 0 0m内的大地电阻率 ,分辨良导介质强 ,不受高阻层屏蔽 ,具有性能稳定 ,轻捷方便等特点 ,同时还具有现场处理分析的功能。文章介绍了EH - 4的设计原理、结构和性能特点及野外工作方法 ,并结合实例介绍了其应用效果 ,最后还分析了电磁勘探在我国的应用前景。
Electromagnetic exploration is an important geological measuring method. EH-4 electromagnetic instrument is produced recently in U.S.A., which can measure the resistivity of earth accurately from several meters to several thousands meters. It is also of the advantages of using conveniene and characteristic reliability. This paper instroduces the principle, construction and property of this kind of instrument.
