“…(14). Consequently, for high flow rates the rate of filtration for large Re numbers is expressed by the general formula (15) After introducing the Darcy number defined as (16) which is a ratio of the viscous friction force to the pres sure force, from expression (15), we obtain (17) According to experimental data [13,14], the depen dence of the Da number on the Re number (15) for large values of can be expressed by the empiri cal equation (18) As it follows from Fig. 3, the upper boundary of the use of Darcy's law is determined by the critical value of the Re number, which varies in the range [1].…”

The simulation of the phenomena of asphaltene particle coagulation and fragmentation in the bulk of petroleum and oil emulsion is considered. In particular, the collision rate was determined and the dis tribution function was constructed with the use of the Fokker-Planck equation. A model of the flow and fil tration of structured oil in a porous medium with high concentrations of asphaltenes, tars, and paraffins is proposed. Models for the adsorption of asphaltenes on the surface of water drops in the course of oil emulsion separation are given.
