FIELD: oil production.
SUBSTANCE: plant comprises column of pump-compressor pipes and fluidic apparatus and packer mounted on the column in series from top to bottom. The housing of the fluidic apparatus receives active nozzle and mixing chamber with diffuser and is provided with the passage for supplying fluid, passage for supplying fluid to be pumped out, and central through passage with a seat for installation of a functional insert. The packer is mounted on the column below the fluidic apparatus. The functional insert in the central through passage is made of a sealing insert provided with the axial passage for cable which holds a geophysical instrument below the fluidic apparatus. The bottom part of the sealing insert has spring-loaded by-pass valve through which the passage for supplying the fluid to be pumped out above the check valve is connected with the under-packer space of the well.
EFFECT: expanded functional capabilities.
