The work considers the mutual influence of the operation of injection and producing wells. According to the results of the interpretation of tracer studies, the presence of seven channels of low filtration resistance was established. Calculations of the pore space volume of highly ntercalationlayers, permeability coefficients, pore channel radii, and mass of the adsorbed indicator are presented. The mass of the tracer lost as a result of diffusion processes is calculated. A method for determining the diffusion coefficient from the results of the interpretation of tracer studies is proposed. It is shown that the bulk of the pumped tracer during the movement from the injection to the production well is “lost” as a result of diffusion. After the technology of alignment of the injectivity profile (runway) in the injection well, the operating period of the producing well is analyzed. After repeated tracing studies, the presence of only one highly ntercalationinterlayer with less permeability and radius of the pore channel was found. The reasons for a slight change in the water cut coefficient after runway technology are established.
