摘要：

The article considers the interaction mechanisms of nanocomplexes of various structures with the surface of pore spaces in the filtration flow of polymer solutions, and gives a comparative analysis of the influence of these mechanisms on the behavior of the porosity and permeability properties of an oil-saturated reservoir. It is shown that using polymers with hyperbranched nanoaggregates enhances the efficiency of oil recovery of productive reservoirs.
