FIELD: mining industry.
SUBSTANCE: device contains body with bypass windows and mounting saddle for insert with jet pump. Made in the insert are pass channel, channel for feeding active substance into jet pump nozzle and channel for feeding drained substance into jet pump. Sealing unit is installed in pass channel with axial channel for letting logging cable through it and pass channel, on which logging devices are installed in the well below jet pump with possible movement thereof along the shaft. Input of channel for feeding active substance is connected to annular space of well, and packing elements are mounted on the insert. The insert and sealing unit are made composed of two parts. Part detachment plane passes through axial channel of sealing unit and pass channel of insert along the sealing unit and the pass channel. Insert parts are connected by bolt connection. Pass channel below sealing unit is made rectangular in its transverse section and formed by longitudinal groove, made of, at least, one part of insert.
EFFECT: expanded functional capabilities of plant due to expanded nomenclature of devices and equipment, which may be used in the well during logging operations.
