Abstract: In this paper, we use a hydrodynamic model of two wells with equal in quantity but different in sign production. The wells are located at a given distance from each other in an unbounded formation. The model is a spaced dipole in which the velocity of the potential fluid flow decreases inversely with the square of the distance from the center of the dipole. The model makes it possible to estimate the size of closed oil inclusions depending on the characteristics of the oil displacement regime in the rated reservoir area. On a flat physical model of the stratum that implements the spaced dipole scheme, experiments were conducted to increase oil recovery by the MFK-1 surfactant composition. It has been experimentally founded that the MFK-1 composition promotes coalescence of oil ganglia and their involvement in the general fluid flow. Thereby, the oil recovery coefficient increases. The injection of the MFC-1 composition into the pumping well significantly increases its intake capacity and, as a result, increases the efficiency of the oil displacement process.
