The research progress of complex resistivity logging technology
复电阻率测井技术的研究进展

At present, a lot of studies have been carried out in China in the field of complex resistivity logging(CRL) technology. This paper focuses on the issues,including the theory research and experimental research of complex resistivity dispersion properties, and CRL tool development and application. Then the domestic progress,in situ tests and geological evaluation of CRL are presented. The paper points out current problems of CRL technology and gives some constructive suggestions to the development of CRL technology.
