Устройство для закачивания скважин используется в нефтегазодобывающей промышленности при цементировании эксплуатационных обсадных колонн. Цель: исключение водоперетока между водоносным и нефтяным пластами, уменьшение металлоемкости. Сущность изобретения: устройство включает корпус с пакерующими узлами по концам, привод раскрытия пакеров и каналы для прохождения растворов, выполненные в виде труб, прилегающих к корпусу. Между трубами размещены перфорационные отверстия, закрытые кислоторастворимыми заглушками. Положительный эффект: повышение нефтеотдачи пласта в 1,5 - 2 раза, уменьшение металлоемкости при изготовлении устройства.A device for pumping wells is used in the oil and gas industry in cementing production casing. Purpose: elimination of the water flow between the aquifer and oil reservoirs, reduction of metal consumption. The inventive device includes a housing with packer nodes at the ends, the drive disclosure packers and channels for the passage of solutions, made in the form of pipes adjacent to the housing. Between the pipes there are perforations, closed with acid-soluble plugs. Positive effect: increased oil recovery by 1.5 - 2 times, reduction of metal consumption in the manufacture of the device.
