description: The subject of the graduate qualification work is "Two-Tube Model of Viscous Fingering under Miscible Displacement of Liquid". This work is devoted to numerical modeling of the process of displacement of viscous fluids with the formation of instability of the Suffman-Taylor-type blowout front in the framework of the Peaceman model approximation. The work was carried out on the basis of Gazpromneft STC, Gazpromneft - Technological Partnerships and the Chebyshev Laboratory at St. Petersburg State University. A numerical two-tube displacement model of viscous liquids was compiled and implemented using the methods of the C ++ and Python 3 programming languages in the framework of the Peaceman model, and an approach was proposed in the problem of finding the location of the displacement front. As a result, the factors influencing the velocity of the displacement front movement and the values of the intermediate concentrations of the polymer in the transition zone were analyzed, also demonstrated the success in practice of the proposed solution in the problem of searching for the front of displacement. Based on the results obtained, the dependences of the velocities of displacement front from polinom degree of the function of fluid viscosity were obtained. These results are fundamental and provide a better understanding of the process of viscous fingering and, thus, about time which need on break of the polymer slug into the oil field.
