FIELD: oil and gas industry. SUBSTANCE: invention can be used to run in wells, to examine strata and to intensify oil and gas influxes. This process consists in moving gear closer to productive pool by means of setting jet-type pump under packer and by means of formation of conduit to feed working fluid to jet-type pump, into space under packer. With this in mind jet-type pump is fitted with lock for its anchoring and with puller for its lifting to surface. Hollow body of gear is equipped with sealing unit to render logging cable leak-proof while sinking and setting jet-type pump and with valve adapter and separation tube with extended members to from conduit to feed working fluid. EFFECT: improved quality and body of information to determine maximum production capabilities of well. 11 cl, 7 dwg
