【摘要】 本文介绍了常温常压和储层条件的温度、压力下ＣＨ油田３０块白云岩样品的电阻率测量结果。研究岩石电阻率随温度、压力变化的规律，岩石电阻率与孔隙度、含水饱和度、矿化度等因素之间的关系，最后导出在不同状态下白云岩的阿尔奇经验公式。实验结果和经验公式的获得对测井数据解释有一定的参考价值。更多还原

【Abstract】 The variations in dolomite resistivities with its porosity,water saturation and salinity both under normal pressure and temperature conditions and under reservoir ones are presented in this paper.From those variations the Archie experimental equations for dolomite in special conditions are derived.Our experimental results and the new equations may be important in geological and geophysical data interpretations.更多还原
