摘要
本文从理论上严格地论述了大地电磁测深曲线静态位移的原理,简单介绍了目前国内外所采用的静校正方法,并着重分析了我们所用的压制表层电性不均匀干扰的办法及其效果。
In this paper,we have given a precise description of the principle of the static shift on MT curves from a theoretical perspective, and a brief introduction of the methods that are used at present for static shift correction. We have also discussed the approaches that we developed and applied in real MT data interpretation with their effects. The use of these approaches undoubtedly helps to raise the precision in real MT data interpretation in the future.
