摘　　要：阳江凹陷韩江组油层HM5、HM6层具有埋深浅、低电阻、泥质含量高、油质轻、储层薄等特点,是典型的低阻油层。介绍了该低阻油层识别的主要难点,并根据邻近油层岩屑荧光对比、MDT取样分析、同深度点油样与岩屑地化对比、邻井壁心分析等分析了产生这些难点的原因,总结了该低阻油层识别的方法,为该类储层的勘探和开发提供技术支持。The oil layers HM5 and HM6 of Hanjiang formation in Yangjiang depression are characterized by shallow buried depth,high permeability and low permeability,It is characterized by low resistivity,high shale content,light oil quality and thin reservoir,It is a typical low resistivity reservoir.This paper introduces the main difficulties in identifying the low resistivity reservoir,According to the fluorescence correlation of cuttings in adjacent oil layers,MDT sampling analysis,geochemical comparison of oil samples and cuttings at the same depth,and analysis of adjacent well core,the causes of these difficulties are analyzed,This paper summarizes the identification methods of the low resistivity reservoir,and provides technical support for the exploration and development of this kind of reservoir.
