摘要
双频组合波电磁测深视电阻率是利用双频电磁波进行地电探测的一种新方法。本文通过对各种典型地电模型视电阻率曲线分析,进一步证明了该视电阻率是进行近区频域电磁测深的一种行之有效的方法,它是电磁响应的单值函数,能客观反映地电断面的电性变化规律。具有压制背景场、突出地电异常的功能。它所表现的对地层的分辨能力和各种特性符合测评的要求。
The apparent resistivity of dual-frequency electromagnetic sounding is a new method of geoelectric measurement with dual-frequency electromagnetic wave. By analysing apparent resistivtiy curves of various geoelectric sections, the present paper has proved the practicability of this method.Being the monodrome function of electromagnetic response, the apparent resistivity can objectively describe electric characteristics of the geoelectric section,suppress the interference of background field, and highlight geoelectric anomalies. Its capacity for distinguishing strata and its characteristics can meet the requirements of sounding.
