Influence of the structure of the pore space of rocks on the wettability and adsorbed fluids of reservoir rocks

Abstract

Theoretical and experimental studies of the effect of the geometry of the pore space on the wettability of collectors have been carried out. The special structure of the pore space of the Talinskaya area of the Krasnoleninsky deposit, due to the heterogeneity of the composition of rocks, leads to heterogeneity in the size and geometry of filtration channels and affects wettability. The specificity of the adsorption of polar components of oil causes changes in wettability and affects the amount of adsorbed oil. Keywords: pore space geometry; adsorbed fluids; wettability.
