摘要
复电阻率测井是基于岩石频散特性发展起来的一种新的测井方法,目前对于复电阻率测井的岩石频散机理还没有一个统一的认识,通过理论和岩石频散实验数据的分析以及柯尔-柯尔模型对实验数据的拟合,初步明确了在小于10 kHz的频率范围内,激发极化效应是引起岩石频散的主要因素,通过模拟井眼环境的岩石频散实验研究,验证了采用电极型电极系结构进行复电阻率测井的可行性.
Complex resistivity logging (CRL) is a newly developed logging technique based on frequency dispersion properties of rocks. However, there is no unanimous understanding towards the frequency dispersion mechanisms of CRL. Through theoretical calculations, rock dispersion experiment analysis, and the experimental data fitting by using Cole-Cole Model, it was proved that the induce polarization effect is the main factor of causing rock dispersion within the frequency range of 10 kHz. It also proved the possibility to apply electrode-type logging instrument for CRL method base on the dispersion property experimental research when simulating the downhole environment.
