Installation of a jet pump for well development and oil production

摘要

The utility model refers to the oil and gas production industry and can be used for oil production and development of wells as directional wells and wells with side trunks equipped with a small-diameter production string. The technical result consists in the creation of a reliable, economical, highly efficient and multifunctional device that allows to reduce costs and time, improve the reliability of the installation and the efficiency of well operation by reducing wear and tear, reducing the time and means for replacing wear parts without lifting tubing and deteriorating the collection properties of the formation. The installation comprises a tubing mounted on a tubing string equipped with a packer, a housing with holes in which a jet pump is installed having a filter shank, under which the sealant is installed, a removable nozzle and diffuser, a receiving chamber and channels connecting the receiving chamber to the bottom of the well, and the diffuser with the holes of the housing. In the housing under the jet pump there is a bushing with a non-return valve. In the inner part of the body, an upper protrusion is provided for landing the jet pump and a lower protrusion for the hub. The sealant of the jet pump is made in the form of a cuff that can change the shape for the size of the tubing during the descent of the jet pump and the transition from one diameter of the tubing to the other. 2 z.p. f-ly, 2 ill.
