Current tituation and review of Complex Resistivity

为了探索复电阻率法未来的发展方向,总结了近年来该方法的发展概况,文中从复电阻率法的仪器设备、数学模型、正反演和应用等方面,介绍了复电阻率法的研究进展.目前,复电阻率法仪器设备主SIP-FUCHS3、V8系统和GDP系列仪器;理论方面,研究较多的数据模型有Cole-Cole模型、理论模型SNP;复电阻率法早期正反演研究主要集中于基于Possion方程的正演模拟,数据处理过程中,进行剔除或分离电磁效应的处理,获得激电异常;近年来出现了基于Maxwell方程的CR正反演研究,数据处理过程无需"去耦"校正,进而阐述了近年来国内外CR正反演和在矿产资源、水文地质等多个领域的应用研究进展.最后,展望了复电阻率法的研究方向:(1)基于Maxwell方程的CR正演计算是研究的前沿和热点;(2)在三维基础上加入时间维的四维CR反演是未来的发展方向.

In order to explore the development orientation of complex resistivity, development situation was summarized in the article. The paper mainly introduced the research progress of complex resistivity from the system of intruments such as SIP FUCHS-3,V8 and GDP series apparatus, characteristics of the electrode arrangement and the methods of inversion. Showing that the instrument develops, On the theoretical side, the study on forward and inversion is concerned on the forward modeling that based on Possion equation. The induced polarization anomaly was obtained after the electromagnetic coupling effects was removed or separated in the data processing. The common model in research is： Cole-Cole model,theory model SNP etc. Decoupling do not need in the data processing, furthermore, discussing the research progress of application in mineral resources, hydrogeology etc and then forward and inversion. Citing application of the complex resistivity method in many fields in recent years. In the end, prospecting of the research direction of complex reisistivity： （1） Electromagnetic forward based on Maxwell equation is research focus and frontier in the future; （2）3D detection adding time- lapse is the development orientation in the future.
