METHOD FOE RECOVERING RESIDUAL NONRECOVERABLE FROM DEPLETED OIL FORMATIONS

摘要

A method for recovering residual nonrecoverable oil comprising dissolving oil in gaseous fluid media and by transferring compressed gas from lower gas-bearing beds to upper depleted oil-bearing stratums and subsequent recovery oil/gas mixture, characterized in that gas from lower highly-pressurized beds overflows through existing wells to the oil-bearing stratum by punching in it a production string of an injection well, an oil-gas condensate pool is formed and accumulated and afterwards recovered in the operational mode.
