1. Способ добычи нефти, включающий откачку из продуктивного пласта через одну скважину нефти на дневную поверхность и сброс отсепарированной воды в пласт двумя насосами, установленными на разных глубинах и откачивающими жидкость из герметично изолированных друг от друга камер, нижняя из которых сообщена с пластом, а верхняя - с дневной поверхностью, производительность нижнего насоса подбирают таким образом, чтобы обеспечить максимально допустимую депрессию на пласт, а его напорными характеристиками обеспечить подъем жидкости из нижней камеры в верхнюю до установленного в верхней камере динамического уровня, производительность верхнего насоса подбирают ниже производительности насоса нижнего на величину, необходимую для подъема динамического уровня в верхней камере за единицу времени, при котором происходит гравитационное разделение фаз на нефть и воду, управляемый клапан сброса воды из верхней камеры в нижнюю регулируют таким образом, чтобы сброс воды в пласт происходил до достижения динамическим уровнем критического нижнего значения, после поступления сигнала о достижении расчетного давления обеспечивают срабатывание клапана на закрытие.1. A method of oil production, including pumping from a productive formation through one well of oil to the day surface and discharging the separated water into the formation by two pumps installed at different depths and pumping liquid from chambers that are hermetically isolated from each other, the lower of which is connected to the formation, and upper - with a day surface, the productivity of the lower pump is selected in such a way as to ensure the maximum allowable depression on the reservoir, and its pressure characteristics to ensure the rise of fluid from the bottom chambers in the upper chamber to the dynamic level set in the upper chamber, the productivity of the upper pump is selected below the performance of the lower pump by the amount necessary to raise the dynamic level in the upper chamber per unit time, at which gravitational separation of phases into oil and water occurs, controlled by a water discharge valve the upper chamber to the lower one is regulated so that the discharge of water into the reservoir occurs until the dynamic level reaches a critical lower value, after the signal about Once the design pressure is reached, the valve is actuated to close. 2. Способ по п. 1, отличающийся тем, что нижний насос служит для перекачивания жидкости из нижней камеры в верхнюю для создания необходимого уровня для гравитационного раздела фаз на нефть и воду.2. The method according to p. 1, characterized in that the lower pump is used to pump liquid from the lower chamber to the upper to create the necessary level for the gravitational separation of phases into oil and water.
