FIELD: pump engineering. SUBSTANCE: in mounting jet pump in tubing string geophysical device is mounted below jet pump and check valve and filter are mounted below geophysical device; then, Ejecting medium is fed to nozzle of jet pump and depression is measured by means of geophysical device; upon attaining stable depression, signal is furnished from geophysical device for jettisoning of perforator without discontinuation of pumping-out formation fluid through filter and check valve by means of jet pump. After influx rate has been attained, delivery of ejecting medium to jet pump is discontinued, geophysical device is removed from tubing string, jet pump is disconnected from valve and is withdrawn from well to surface. Then, pump for production is mounted on tubing string in well above check valve and pumping medium out of well is started. EFFECT: possibility of optimization of production of various media from well. 3 dwg
