Overview

The instrument is based on Darcy's law of linear penetration to determine the permeability of gases to rocks.When measuring,the pressure difference is first established,and the inlet pressure of the core and the volume flow of the gas through the core are measured,and then the permeability is calculated according to Darcy's law.

Main technical parameters

1,testing gas:nitrogen;

2,permeability range:0.01 to 3000mD;

3,testing pressure:0.2MPa(mid-high permeability),1.2MPa(low permeability);

4,testing error:low permeability≤10%,mid-high permeability≤5%;

5,testing method:Gas mass flow meter (import);
