ABSTRACT
the permeability of porous media is an important index to characterize the permeability of fluid to porous media. In order to accurately determine the gas permeability of rock medium, a set of steady permeability measurement system is designed. The measurement and control part of the system is designed based on the Labview platform, and the functions of sensor control, acquisition, data processing and storage are realized. The experiment of gas permeability measurement and its uncertainty evaluation were carried out, and the results showed that the measurement system had good repeatability, and the extended uncertainty was 1.9%, which met the requirement of material permeability measurement.
