大地电磁法作为沉积盆地普查测量和地热区目标勘探的有力工具,应用已经很久了。但长期以来,它还存在着三方面的严重缺陷:(1)不能解决复杂的地质结构;(2)易受静态畸变的影响;(3)易受人为的电磁干扰。
Magnetotelloy has been used for a long time as a powerful tool for the census surveys of sedimentary basins and exploration of geothermal targets. But for a long time, there are still three serious flaws: (1) can not solve the complex geological structure; (2) susceptible to static distortion; (3) susceptible to human-induced electromagnetic interference.
