Claims (2)

1. Способ эксплуатации нефтяной залежи с поддержанием пластового давления, включающий скважину, в которой два пласта - водонасыщенный и нефтенасыщенный - соединены путем перфорации обсадной колонны, отличающийся тем, что в скважине, пробуренной как минимум с двумя разветвленными стволами, в одних разветвленных стволах вскрыт только нефтенасыщенный пласт, а в остальных - одновременно водо- и нефтенасыщенные пласты, причем разветвленные стволы (ствол) вскрывающие нефтенасыщенный пласт, сообщены с устьем скважины, а разветвленные стволы (ствол), вскрывающие одновременно нефтенасыщенный и водонасыщенный пласты, разобщены от устья скважины.1. A method of operating an oil reservoir with maintaining reservoir pressure, comprising a well in which two reservoirs — water-saturated and oil-saturated — are connected by perforation of the casing, characterized in that in a well drilled with at least two branched trunks, only branched trunks are opened oil-saturated formation, and in the rest - at the same time water and oil-saturated layers, with branched trunks (trunk) opening the oil-saturated layer, communicated with the wellhead, and branched trunks (st ol), at the same time revealing the oil-saturated and water-saturated layers, separated from the wellhead. 2. Способ по п.1, отличающийся тем, что на участке ствола между вскрытыми нефтенасыщенным и водонасыщенным пластами установлены расходомеры и регуляторы расхода воды.2. The method according to claim 1, characterized in that in the section of the barrel between the opened oil-saturated and water-saturated formations, flow meters and water flow controllers are installed.
