多温度多矿化度岩石电阻率实验研究

Experiment study of rock resistivity with multi-temperature and multi-salinity.

多温度、多矿化度岩石电阻率实验研究表明 ,岩石的电阻率、视地层因素、视胶结指数、视电阻率增大系数、视饱和度指数与地层温度、地层水矿化度、泥质含量等因素有关。在利用阿尔奇公式进行含油性评价时 。

Experimental study of rock resistivity with multi temperature and multi salinity shows that rock resistivity,apparent formation factor,apparent cement exponent,apparent resistivity increasing coefficient and apparent saturation exponent are related to such factors as formation temperature,formation water salinity and shale content etc.A relevant correction for Archie's parameters is needed when Archie's formulae are used to evaluate oil saturation.
