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 future development direction of the complex resistivity method, the development of the method in recent years is summarized. In this paper, the complex resistivity method is introduced from the complex resistivity instrument equipment, mathematical model, inversion and application At present, the complex resistivity instrumentation equipment SIP-FUCHS3, V8 system and the GDP series of instruments; theory, the more data models studied have Cole-Cole model, the theoretical model SNP; Early inversion of complex resistivity method The main focus is on forward modeling based on Possion equation. During the data processing, exclusion or separation of electromagnetic effects is performed to obtain the anomalies of the anomalies. In recent years, CR forward and backward inversion based on the Maxwell’s equation has emerged. The data processing process does not require “ Decoupled ”correction, and then elaborated in recent years at home and abroad CR positive and inversion and application in mineral resources, hydrogeology and other fields of research progress.Finally, the prospect of complex resistivity research: (1) based on Maxwell The equation of the CR forward calculation is the frontier and hotspot; (2) Based on the three-dimensional time dimension of the four-dimensional CR inversion is the future direction of development.
