Abstract:

The article describes a mechanism of oil displacement in the tertiary stage of field development. It is shown that the most important element in solving the problem of residual oil displacement can be periodic (quasi-periodic) hydrophobizator adsorption on the walls of collectors. The paper presents the analytical model of the oil phase acceleration, as well as the results of mathematical modeling of filtration in a periodically hydrophobized collector.
