Abstract
The paper discusses the relationship between the filtration properties and the reservoir filter channels distribution density. In this case, the Brooks-Corey model was used, allowing the capillary curves obtained in laboratory conditions for the Las-Egansk field BV6 reservoir approximating with good accuracy. It is shown that the pore channels of collectors in Western Siberia distribution moments are completely determined by the approximation model parameters. With a known absolute permeability, the parameters of the Brooks-Corey model are estimated first, and then the filtration channels moments of distribution are determined. The paper presents expressions that allow one to proceed from the Brooks-Corey model parameters to the pore channels distribution moments over radii. Graphs of pore channels distribution density are presented for various absolute permeability values.
