A Two-Dimensional Network Model to Simulate Permeability Decrease Under Hydrodynamic Effect of Particle Release and Capture

摘要: A model was developed to simulate permeability decrease induced by hydrodynamic effects when injecting a fluid in reservoir with respect particle release and capture mechanisms the parameters of fluid–rock system. The kinetics were integrated after computing initial porous medium square lattice two–dimensional network model. rate is related difference between microscopic velocity critical velocity. shows direct link reduction pore throat radii three capture: straining accumulation through interception or diffusion. Comparison simulations experimental results that reproduces physics phenomenon, although values are overestimated. two sets can be explained fact realized at constant pressure whereas experiments flow rate, re–entrainment trapped particles not taken into account
