FIELD: oil and gas industry.
SUBSTANCE: group of inventions relates to oil industry and can be used for mounting installations of electric-centrifugal submersible pumps (ESP) on a load-carrying cable. Mounting method includes arrangement of extractable packer on lower end of tubing string, successive installation of cable suspension unit, X-mas tree, block of preventers and lubricator with sealing unit, lowering through lubricator into tubing string using load-carrying cable of electric-centrifugal pump and plug-in cutoff valve, docking shut-off valve with seat and connection of load-carrying cable upper end to cable suspension unit. Cable suspension unit is arranged above X-mas tree, extractable packer is suspended to electric-centrifugal pump and lowered together with shut-off valve into well through lubricator. Method can be used for installation of plants in the non-dead wells both without preliminary preparation of the submersible equipment in the well, and for installation in the well, in which there is ESP, for example, failed.
EFFECT: inventions are aimed at simplification of ESP installation process on load carrying cable and reduction of labor intensity due to elimination of additional costs for round-trip lifting of tubing.
