Abstract

1. Внутрискважинное устройство одновременно-раздельной закачки агента, содержащее смонтированные на колонне насосно-компрессорных труб пакеры и блок регулирования потоков и учета расхода закачиваемого агента телемеханической системы, включающий дроссельные клапаны, объединенные блоком электроприводов, датчики телеметрии и расходомер, последние размещены в полостях гильз, параллельно расположенных в корпусе, ограниченном снизу прямоточной многоканальной муфтой, и связаны геофизическим кабелем, пропущенным через устьевую запорную арматуру, с контрольно-измерительными приборами на станции управления, при этом нижний торец ствола верхнего пакера соединен с радиально-проточной муфтой, в центральном отверстии последней расположен конец хвостовика, образующего со стволом верхнего пакера коаксиальные проточные каналы раздельной закачки агента в нефтеносные пласты, отличающееся тем, что корпус и гильзы блока регулирования потоков и учета расхода закачиваемого агента выполнены герметичными, для чего корпус блока сверху ограничен впускным коллектором, сообщающим полость колонны насосно-компрессорных труб с полостями гильз, а в блоке электроприводов дроссельных клапанов выполнен аксиальный патрубок, сообщающий колонну насосно-компрессорных труб с коллектором, причем на входе в патрубок установлен датчик давления закачиваемого агента, связанный геофизическим кабелем с контрольно-измерительным прибором, размещенным на станции управления, при этом на входах расходящихся каналов коллектора выполнены запорные седла, взаимодействующие с дроссельными клапанами.2. Внутрискважинное устройство одновременно-1. The downhole device for simultaneous-separate injection of an agent containing packers mounted on a column of tubing and a flow control and flow metering unit for the injected agent of the telemechanical system, including throttle valves combined by an electric actuator block, telemetry sensors and a flow meter, the latter are located in the liner cavities, parallel located in the housing, bounded below by a direct-flow multi-channel coupling, and connected by a geophysical cable passed through the wellhead shutoff valve, with instrumentation at the control station, while the lower end of the upper packer barrel is connected to the radial flow coupling, in the central hole of the latter there is the end of the shank, which forms coaxial flow channels of separate injection of the agent into the oil reservoir with the upper packer barrel, characterized in that the casing and sleeves of the flow control unit and the metering agent for the injected agent are sealed, for which the casing of the unit is bounded from above by an intake manifold reporting the floor the tubing string with sleeve cavities, and in the throttle valve electric actuator block an axial pipe is made that communicates the tubing pipe with the manifold, and at the inlet to the pipe there is a pressure transducer of the injected agent, connected by a geophysical cable to the measuring instrument placed at the control station, at the same time, locking saddles interacting with throttle valves are made at the inputs of the divergent channels of the collector. 2. Downhole device at the same time
