Abstract
To study the possibility of creating samples with known values of the absolute gas permeability coefficient, a comparison was made between the results of measurements of the absolute gas permeability coefficient and theoretical calculations of the values of the permeability coefficient of samples with built-in glass capillaries of various diameters. The results of measurements of the absolute gas permeability coefficient were obtained on the State primary standard of units of specific gas adsorption, specific surface area, specific pore volume, pore size, open porosity and gas permeability coefficient of solid substances and materials GET 210-2019. The theoretical values of the permeability coefficient were obtained by measuring the diameters of capillaries with an optical microscope. Using these diameters, the permeability coefficients of samples with capillaries were calculated according to the combined Poiseuille and Darcy equation. It is proved that the measurement results obtained at GET 210-2019 are consistent with the theoretically calculated values of the permeability coefficient within the limits of uncertainty. The results obtained will be useful to specialists of the oil and gas industry, for example, in petrophysical research, geological exploration.
