Abstract

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
