摘要
含油岩石电阻率与饱和度关系的理论基础是经典的阿尔奇公式,它是在实验室条件下对纯砂岩提出的,因此公式中的参数受到很多因素的影响。本文系统总结了阿尔奇公式中参数的影响因素,并在此基础上分别讨论了孔隙结构、温度、压力、泥质含量、润湿性和矿化度等对胶结指数和饱和度指数的影响,深入分析了它们对阿尔奇公式影响形式的复杂性问题。通过本文的分析,为进一步的研究奠定了理论基础。
The relationship between resistivity and saturation of oil-bearing rocks is based on the classical Archie equation which is proposed under laboratory conditions.So parameters in the formula are affected by many factors.This paper summarizes the influencing factors of Archie parameters systematically.It discusses the effect of pore structure,temperature,pressure,shale content,wettability and salinity on the cementation exponent and saturation exponent.It gives deep analysis about the complex impact on Archie equation.It lays a theoretical foundation for further research.
