METHOD OF OIL POOL DEVELOPMENT

摘要

oil producing industry. SUBSTANCE: method includes injection of working agent through injection wells and oil withdrawal through producing wells, selection of producing well with maximum water encroachment; determination for this producing well of injection well with maximum coefficient of correlation between its injectivity and flow rate of fluid of selected producing well; shutoff of all other producing wells hydrodynamically connected with injection well, injection of emulsion-forming composition into injection well and selected producing well with maximum water encroachment; starting of all shutoff wells operation. Offered method provides increase of oil recovery from oil pool due to fuller development of nondeveloped oil-containing interlayers found in inundated part of formation due to zonal selective action on reservoir. Through producing and injection wells. EFFECT: higher oil recovery from formation, reduction water cutting of recovered production and volumes of associate produced water. 1 ex
