Factors that affect permeability of rocks
WebMay 22, 2024 · The plasticity index, average pore diameter, and particle size distribution of cohesive soil affect its permeability, resulting in changes to the hydraulic gradient and seepage velocity. The function describing the relationship between these influencing factors and hydraulic conductivity can be obtained with the single factor test. WebApr 8, 2024 · The effects of controlling factors, including flow rate, fluid kinematic viscosity and DFN aperture for jointed reservoirs and flow rate, fluid kinematic viscosity and block strength in conglomerate ones, are studied. The results show that the high fracture density DFNs strongly affect the HF propagation pattern and fluid pressure rise.
