Abstract: FIELD: oil industry. SUBSTANCE: in correspondence with proposed process multiphase fluid is sampled from production wells. Working substance is pumped into injection wells. Pulse hydrodynamic conditions are formed by opening and shutting off of injection and production wells. Hydraulic and piezo conductance of pools is determined. Disturbing wells are chosen in flooded and oil zones under pulse actions. Components of field of hydraulic conductance in forcing and oil phases are determined for different periods by presented dependence. Optimum conditions per each production well are calculated from conditions of maximum oil outputs with simultaneous prevention of more than twofold drop of hydraulic conductance in forcing phase with reference to calculated maximum one and with setting of face pressure in injection wells at value by not more than 10 MPa above initial pool pressure. Basic period per each well is found by presented dependence. Combination of actions of two levels is realized. Periodic operational conditions with different periods in one order (with rise) and in another order (with decrease) under action of first level are set. Pool is exploited to flooding. When high water content is achieved operation transfers to action of second level. Operational conditions change till water content is corrected and water content is monitored. Operations are repeated with change of average water content. EFFECT: expanded application of non- stationary methods of exploitation of oil fields and additional extraction of oil from localized sections.
