Zusammenfassung:	For extracting oil from wells, pipe string, packer with axial through hole and support with axial channel with seat for jet pump mounting. Bypass channel with return valve is in support wall. Pump has cylindrical body with annular shoulder, for support seat mounting. Body has channel for supplying active medium to the pump nozzle, channels for supplying pumped out medium and removing media mixture and through channel with sealing unit. The channel couples to unit downstream channel. The unit has axial channel passing and displacing a logging cable/instrument. Mixing chamber with diffuser connected to the pipe string cavity upstream of pump positions axially to the nozzle. Channel diameter of support downstream of seat is equal to or greater than packer hole. The invention makes it possible to extend the device functionalities due to the possibility of disconnecting the in-tube space and casing annulus when the pump is stopped.
