摘　　要：复电阻率测井（CRL）是我国电法测井研究工作者根据岩石电阻率频散特性提出和发展起来的一种方法。从理论角度看，其区别于其它常规电测井方法的主要特征为：复电阻率测井把电性参数的频散特性作为测井评价储层含流体性质的主要依据，有望在剩余油评价、特殊矿化度地层评价等方面提供有效的手段。本文首先介绍复电阻率的定义、电阻率频散的概念和复电阻率测井的原理，然后结合电极型复电阻率测井仪器的油田应用实例，探讨其在剩余油评价方面的应用可能性和有效性，并指出了其研究应用前景。Complex resistivity logging (CRL) is an electrical logging method which was developed according to the frequency dispersion characteristic of rock resistivity by Chinese researchers.The feature that the frequency dispersion of rock electrical parameters could be applied to the for- mation evaluation is the main advantage of CRL which is different from the conventional electrical logging.This paper presents the definition of the complex resistivity,concept of resistivity frequency dispersion and logging principle.Combining with the application examples of the electrode-type logging tool in the oilfield,it discusses the possibility and validity in remaining oil evaluation,and gives out the application prospects.
