Abstract
The metrological support of measurements of the absolute gas permeability coefficient of rocks is considered. It is shown that in some cases it is impossible to determine the absolute gas permeability coefficient with the required accuracy. An algorithm has been developed for processing the measurement results of the absolute gas permeability coefficient of rocks by the stеady-state method. The algorithm is based on the combination of equations describing Darcy's law and the Klinkenberg’s effect, its application makes it possible to increase the accuracy of measurements of the specified absolute gas permeability coefficient. The results of experimental and model (theoretical) studies are presented. Using the Monte Carlo method, it is theoretically proved that the use of the proposed algorithm for processing primary data reduces the uncertainty of measurements of the absolute gas permeability coefficient by 1.5 times compared to the existing algorithm. The theoretical data are consistent with the experimental results of measurements of the absolute gas permeability coefficient of 50 corundum samples. The scope of application of the results obtained: oil and gas industry, geology, scientific research.
