SIMULATION OF ANOMALOUS OIL FILTRATION IN A POROUS BED

The problems of modeling the processes of filtration of anomalous structurized oils with coagulation structures present in a porous bed are considered. An equation for the fi ltration of Bingham fluids in a carrier bed that accounts for the dependence of the fi ltration rate on the pressure gradient and shear stress has been derived. Models for calculating the effective viscosity and mobility of oil depending on the change of the pressure gradient in the bed and of the concentration of particles in it have been developed. A comparison of these models with the experimental data available in the literature for various wells yielded satisfactory results.
