FIELD: operation of oil wells, particularly, producing well logging. SUBSTANCE: device has packer installed on pipe string jet pump with active nozzle, mixing chamber, diffuser and shutoff member with seat installed parallel to jet pump. Passed through axial channel of shutoff member is logging cable connected to geophysical instrument. Packer is inflated by fluid pressure and installed on jet pump casing against mixing chamber where jet pump casing has holes for supply of working fluid to packer. EFFECT: reduced time for setting and removal of packer and higher pumping capacity of jet pump. 2 cl, 1 dwg
