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。

Abstract: 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.

Key words: Core, Electical resistivity, residual air, in jesting CO2, vacuum saturation
