EXPERIMENTAL DETERMINATION OF THE FILTRATION FLOW PROPAGATION VELOCITIES BASED ON THE AIR FLOW. IN ROCK CORES

摘要

The experimental procedure and test data on assessment of rates of air filtration flow are reported. Permeability of the test specimens differ by more than four orders in the range of linear filtration. The tests with core specimens under the gas pressures of 0.5, 1, 2, 5, 10 MPa established relationships between the gas propagation rate, gas pressure, structure and hydrodynamic characteristics of the specimens.
