Claims (2)

1. A method of developing an oil reservoir, including the selection of oil through production wells and water injection in a cyclic mode through injection wells, characterized in that the parameters of the reservoirs of the productive horizon are determined and the duration of the half-cycles of the cyclic mode of water injection through injection wells is established, at the beginning of the first half-cycle into injection reagents are injected into the highly permeable intervals of the section of the productive horizon, increasing the hydrodynamic resistance of the reservoirs and maintaining They exhibit these properties during the time of the first half-cycle and then pump water throughout the entire first half-cycle; during the second half-cycle, water is pumped into injection wells over the entire interval of the production horizon section.  2. The method according to p. 1, characterized in that the injection of reagents that increase the hydrodynamic resistance of the formations is carried out by introducing them into the stream of water pumped into the injection well while maintaining the injection mode.
