摘要
本文提出了在岩石抽真空饱和过程中注入ＣＯ２气体取代残余空气分子，从而减小岩石电阻率测量误差的方法．实验结果表明，该方法比常规抽真空饱和方法提高测量精度近１０％．为此，研制了岩石电阻车测量中注ＣＯ２气抽真空饱和的处理程序．
This paper present a method to replace in a process of vacuum saturation the residual air with injecting CO2 gas so as to reduce the error in the measurement of electrical resistivity.The results of a series of experiments show that this method has improved the conventional method of vacuum saturation and almost increased the accuracy of the measurement by 10%.In addition,a better experimental process is also suggested in this paper.
