The inventive device operating method consists in running a jet pump into a well, in releasing a packer above a productive formation, in pumping a hydraulic fracturing fluid into the formation though a blocking insert in the pump channel, in extracting said blocking insert, in running a flexible pipe into the well through a sealing unit and in arranging the lower end thereof at a level of a lower formation perforation interval. When the formation is drained, the method consists in supplying a fluid for washing a bottomhole by means of the flexible pipe and maintaining the ratio between the pressure value in said flexible pipe and the working medium pressure in a casing annulus within a range of equal to or greater than 0.98. When at least two volumes of hydraulic fracturing fluid pumped into the formation is pumped out, the fluid supply in the flexible pipe is stopped. After than and not early than in 5 minutes, the inventive method consists in shutting off the working medium supply to the pump nozzle, in examining the formation for evaluating the productivity thereof and in bringing the well into operation. Said invention makes it possible to intensify well examining, testing and preparing works and to increase the reliability of data on the well operating readiness.
