可控源音频大地电磁测深法应用研究综述

Review on Application of CSAMT

与常规物理勘探手段相比,可控源音频大地电磁法(CSAMT)具有勘探深度大、抗干扰能力强、工作效率高及分辨率高等特点,因此其被广泛应用于地下热水勘探、地质构造探测、隧道勘察,以及金属矿产勘查等,并取得了良好的勘查效果。通过对可控源音频大地测深法在不同领域应用现状的综述并举例说明,笔者认为可控源音频大地测深法作为一种地球物理勘探手段,拥有着其他物探手段无法比拟的优点,在现阶段具有不可替代性。

Compared with the conventional geophysical exploration methods, the controlled source audio magnetotelluric method （ CSAMT ） has great exploration depth, strong anti-interference ability, high efficiency and high resolution, so it is widely used in underground water exploration, geological exploration, tunnel exploration, and metal mineral exploration and achieved good effect of exploration. Through the overview of controlled source audio frequency magnetotelluric sounding method application in different fields and illustrates, the author thinks that the controlled source audio frequency magnetotelluric sounding method as a kind of geophysical exploration methods, with other geophysical methods can not match the advantages, which can not be replaced.
