FIELD: oil production. SUBSTANCE: plant includes receiver-converter of physical fields, tool for ultrasound stimulation of bed separable functional inserts and inlet funnel with tail, packer with central passage cut in it and jet-type pump mounted on pipe-string from beneath upwards. Body of jet-type pump houses active nozzle and mixing chamber, passage to supply active medium, passage to feed medium pumped from well and stepped flow passage with location seat between steps. Sealing unit is installed in turn in stepped flow passage, it can move along logging cable or wire above tip for connection of receiver-converter of physical fields or tool for ultrasonic stimulation of bed and separable functional inserts ( depression insert and insert to record curves of reconstruction of formation pressure ) in space of well above packer. Plant also has sampler and autonomous instrument. Tool for ultrasound stimulation of bed includes ultrasonic radiator that emits on two ultrasound frequencies and pressure transducer. EFFECT: increased inflow of extracted medium. 3 dwg
