FIELD: technology for extracting various substances from wells.
SUBSTANCE: in accordance to the method, packer and jet pump are lowered into the well between productive beds, packer is installed between lower and first intermediate formation, hydro-fracturing liquid is forced into lower formation, then drainage of the bed is performed with removal of hydro-fracturing liquid from it together with proppant non-fixed in the bed, recording pressure in the well below the packer by means of autonomous manometer, after that packer is switched to transport position, pipes column with packer and jet pump is lifted and packer is unpacked between next intermediate beds, proppant seal is installed in interval from the face to the shoe of intermediate bed, then operations are repeated, and so on depending on number of productive layers, after that flexible tube is lowered through pipes column and jet pump and well is cleaned of proppant through it, after removal of proppant depression is created on productive beds and by means of geophysical device influx profiles are registered in interval from well face to entrance cone.
EFFECT: increased operational productivity of well jet plant.
