FIELD: jet pumping units for oil recovery from wells. SUBSTANCE: pumping unit has jet pump installed on pipe string in cased well. Installed coaxially in pump case is active nozzle with mixing chamber and through channel with landing place for mounting of sealing unit with axial channel or changeable functional inserts with autonomous instruments. Pump outlet is connected to well annular space. Inlet of channel of working medium supply to pump active nozzle is connected to internal space of pipe string above sealing unit. Channel of inlet of medium pumped from well is connected to internal surface of pipe string below sealing unit. Pumping unit is provided with radiator and receiver-converter of physical fields and packer. Pump and packer are located in well below casing string. Pipe string has turning device located between pump and packer. Part of pipe string above turning device is installed for turning relative to pipe string part located below turning device by means of drive located on ground surface. Turning device is located above packer at a distance not shorter than packer outer diameter. EFFECT: increased efficiency and accuracy of acquisitioned information in conduction of researches. 1 dwg
