Key words: jet pump, operation of marginal wells
In Gazpromneft-Khantos LLC started the pilot tests of jet pump units at marginal complicated well stock. On Priobskoye field the jet pumps will be used with single-pipe arrangement, packer and telemetry system. The reservoir pressure maintenance system will serve as the source of energy. In operation of these settings the hydraulic fluid is pumped through tubing in the nozzle of the jet pump, and the mixed flow of the hydraulic and reservoir fluids rises to the surface through the annular space between the tubing and the production casing of the well. With the telemetric system the pressure measurements are made above and below the packer and are transmitted to the surface by cable. Submersible jet pump can be removed if necessary from the wellbore to replace the flow part by hydraulic method. This avoids the replacement of downhole equipment without costly workover and well killing, which significantly improves the overhaul period of wells.
