Abstract
The study presents the results of comprehensive research on the efficiency of using polymer systems with nanoaggregates as oil displacement agents. Laboratory tests included experiments to determine the oil displacement coefficient on linear core models, as well as experiments to determine the oil recovery factor using parallel flow tubes of varying permeability, simulating the implementation of polymer flooding technology in stratified-heterogeneous oil-saturated reservoirs. The results of hydrodynamic studies using parallel flow tubes with polymer systems containing nanoaggregates demonstrated a significantly greater redistribution effect of filtration flows compared to traditional polymer solutions. The theoretical modeling of the polymer flooding process was conducted based on a percolation-hydrodynamic model, accounting for the specific flow characteristics of polymer systems with nanoaggregates in a porous medium. A comparison of the theoretical results with laboratory test outcomes showed good agreement.
