Claims (3)

1. Установка для вытеснения нефти из пласта, включающая последовательно соединенные насос, сепаратор и эжекторное устройство, установленное внутри нагнетательной скважины, отличающаяся тем, что эжекторное устройство установлено на забое нагнетательной скважины и дополнительно снабжено обратным клапаном, размещенным в месте ввода газа в устройство.1. Installation for displacing oil from the reservoir, including a series-connected pump, separator and ejector device installed inside the injection well, characterized in that the ejector device is installed on the bottom of the injection well and is additionally equipped with a check valve located at the gas inlet to the device. 2. Установка по п.1, отличающаяся тем, что линия насосно-компрессорных труб нагнетательной скважины соединена с затрубным пространством добывающих скважин. 2. Installation according to claim 1, characterized in that the line of the tubing of the injection well is connected to the annulus of the producing wells. 3. Способ вытеснения нефти из пласта, включающий одновременную закачку воды и газа по раздельным линиям, образования в стволе скважины эжектированием водогазовой смеси и вытеснение нефти к добывающим скважинам, отличающийся тем, что закачку воды осуществляют по затрубному пространству нагнетательной скважины, а газа по насосно-компрессорным трубам, в нагнетаемую воду периодически добавляют поверхностно-активное вещество концентрацией 0,5-1,1%, а затем, после срабатывания обратного клапана эжекторного устройства, проводят кислотную обработку пласта с использованием растворов кислот, образующих водорастворимые соли при контакте с карбонатным скелетом породы. 3. A method of displacing oil from the reservoir, including the simultaneous injection of water and gas in separate lines, the formation in the wellbore by ejecting a water-gas mixture and the displacement of oil to production wells, characterized in that the water is pumped through the annulus of the injection well, and gas is pumped to the compressor pipes, a surfactant with a concentration of 0.5-1.1% is periodically added to the injected water, and then, after the check valve of the ejector device is activated, acid treatment is carried out formation overburden using acid solutions forming water-soluble salts upon contact with the carbonate skeleton of the rock.
