Beschreibung
Zusammenfassung:	FIELD: oil producing industry; applicable in development of oil pools with bottom water. SUBSTANCE: method involves oil withdrawal form formation oil-saturated zone until water coning; installation of packer at level of water-oil contact; creation of water-impermeable interval by injection of isolating composition; subsequent resuming of oil withdrawal; additional perforation of well in water-saturated zone of formation for formation of hydrodynamic communication between oil- and water-saturated zones of formation. Isolating composition is injected through perforation interval in oil- or water-saturated zone of formation. EFFECT: higher efficiency of oil production method in pools complicated by breakthroughs of underlying formation water into oil-saturated zones. 2 cl, 2 dwg, 2 ex
