Measurement of Gas-Dynamic Parameters of Superheated Gas Flow in Slit, Applicable to the Bazhenov Formation
The paper describes the results of a laboratory study of the filtration of hot gas flows in a gap during the evaporation of its walls as applied to the Bazhenov formation. The slit imitated a crack in a shale layer, which was modeled by plexiglass plates that make up the cell. The slit was blown by heated gas flows. During the experiment, a change in the mass of the cell and a pressure differential was recorded, on the basis of which the flow rates were estimated. The evaporation rate and ablation of the mass of material from the surface of the slit were also measured. The flow measurement technique presented in the work allowed determining the coefficient of extraction of liquid and gas phases of hydrocarbons from shale.
