Abstract:

This paper presents a new method of steady flow to solve the problem that the injection rate into cores is difficult to get steady, especially for gas in measuring relative permeability. Here, the pressure-controlled capillary tube constant flow apparatus is used rather than micro-injection pump. This method has been proved to be practicable both theoretically and experimentally in this paper.

Key words: Core analysis, Relative permeability, Laboratory Apparatus
