导电机理研究是用电阻率测井定量计算饱和度的理论基础,是选取解释模型与处理参数的理论依据,探讨导电机理对正确计算饱和度具有重要意义。根据通用化的Maxwell方程及Fricke等的研究成果,首次提出“港湾效应”。以“港湾效应”导电机理为基础的饱和度方程综合考虑了背景电阻率、孔隙结构及不导电孔隙度等因素,进一步发展了Maxwell及Fricke的方法,在复杂岩性储层饱和度计算中见到了好的应用效果。
Conducting mechanism research is the theoretical basis for quantitatively calculating saturation by resistivity logging, and is the theoretical basis for selecting the interpretation model and processing parameters. It is of great significance to study the conductive mechanism for the correct calculation of the saturation. According to the universal Maxwell equation and Fricke and other research results, for the first time proposed “Harbor effect ”. The saturation equation based on the “Harbor effect” conduction mechanism takes into account factors such as background resistivity, pore structure and non-conductive porosity, and further develops the Maxwell and Fricke methods. In the calculation of reservoir saturation in complex lithology In the good application of the effect.
