Annotation:

The authors of the article assess the effectiveness of the polymer flooding technology, where the displacing agent is a polymer system enhanced by the addition of nanomaterials. The assessment includes both theoretical and laboratory studies of the process under consideration. The theoretical calculations were based on a percolation-hydrodynamic model, which accounts for the specifics of the micromechanics of polymer particle deposition on the porous medium framework. The experiments were conducted in several stages and included the study of the polymer system dissolution time, its viscosity and the kinetics of a stable structure formation. Filtration studies were carried out to determine the oil recovery factor using a linear reservoir model. When modeling the polymer flooding process in a stratified heterogeneous reservoir, laboratory tests were conducted on parallel flow tubes with varying permeabilities. When polymers with nanomaterial additives were used, a significantly higher oil recovery increase was observed from the low-permeable flow tube compared to conventional polymer solutions. A comparison of the theoretical results with laboratory test outcomes demonstrated good agreement.
