experimental Findings on evaluation of velocity of the filtration-disturbance propagation with an air flow within rock cores
The experimental procedure and test data on evaluation of the velocity of the filtration-disturbance propagation are reported. Permeability of the test specimens differ by more than four orders over a range of linear filtration. Observations are performed at gas pressure of 0.5, 1, 2, 5, 10 MPa in specimens. The authors established dependences of the rate on gas pressure, structure and hydrodynamic characteristics of specimens.
