Annotation:

A new complex technology for increasing oil production based on the energy recovery of the water-flooding system is proposed. The scientific and technical literature on the relevant topics was analytically reviewed, a complex technology was described, a technological scheme was developed, criteria for selecting an implementation object were formed and laboratory studies of the kinetics of the process of the emulsion formation and separation were carried out to prevent complications when implementing the technology. Numerical simulation was also performed in the Ansys CFX software. According to the results of the pilot tests, the volume of additional oil production can be 3,48 tons/day (an increase of more than 5 %) or more, which proves the practical significance of the developed integrated technology.
