我们将实验室测得某钻孔36个灰岩标本干燥情况下的电阻率值与该孔相应深度电阻率测井剖面进行对比,导出一个阿尔奇公式的修正形式,使得实验测得干燥岩石电阻率和电测井视电阻率吻合很好。
We compare the resistivity of dry samples of 36 limestone samples from a borehole in a laboratory with the corresponding resistivity log of the borehole and derive a modified version of the Archie formula so that the experimental dry rock resistance Rate and electrical logging apparent resistivity in good agreement.
