FIELD: oil industry. SUBSTANCE: this method may find use when exploiting inhomogeneous oil field at late stage. Method of exploitation of inhomogeneous oil field includes pumping of working agent through injection holes, extraction of oil through production wells and stopping of production wells with ultimate water content of extracted product. In compliance with invention in field there are selected sections located within zone of influence of injection holes supplied from one source of working agent, low-discharge production wells and injection holes with high and low acceptance characteristic are selected, seam pressure in low discharge production wells is decreased by 20-45%, injection holes with high acceptance characteristic are stopped and pumping pressure in injection holes with low acceptance characteristic is increased by 10-20% with preservation of relation of volumes of pumping and extraction within limits of developed section. Production cells with ultimate water content in extracted product can be stopped for 5-7 months or exploited for 5-7 months under cyclic mode: 0.5-1.0 month of stopping and 0.5-1.0 month of exploitation. EFFECT: increased oil output of field. |
