Abstract
When evaluating the reservoir, it is extremely important not only to determine the porosity & permeability but also to understand the fluid flow through the reservoir.
According to a complex of laboratory studies of reservoir rocks from the West-Shebelynska area (interval depths 4929–5380 m), the authors are compared the methods of assessing the reservoir properties. It is shown that the estimation of the void structure and the hydraulic flow units allow locating promising intervals to the same extent. Using multiple linear regression, the relationship between permeability and different types of voids are established.
Correlation dependence between the reservoir quality index and the total volume of secondary voids and fractures are built. It is established, that fluid filtration in the studied samples occurs mainly through the secondary voids and fractures.
Key words: reservoir rocks, fluid filtration, hydraulic flow units, void structure.
