Permeability Evolution and Particle Size Distribution of

AbstractIntroductionExperimental Materials and Testing MethodsCalculation of Fractal Dimension and PermeabilityResults and DiscussionConclusionsConflicts of InterestAcknowledgmentsIn this research, the particle size distribution and permeability of saturated crushed sandstone under variable axial stresses (0, 2, 4, 8, 12, and 16 MPa) were studied. X-ray Computed Tomography results revealed that particle crushing is likely to occur considerably as the axial stress is approaching 4 MPa, which results in the change of pore structure greatly. During compression, the particle size distribution satisfies the fractal condition well, and the fractal dimension of particle size distribution is an effective m
