FIELD: oil and gas industry.
SUBSTANCE: method includes well washing and gaging, trip with block-after-block installation of the well equipment, and well fluid production. Initially the bottom block is lowered, it contains funnel, bottomhole and supporting packers with straight-flow coupling, in it tubular elements with bells of the extendable pipe connection, they are successively screwed together in the wellhead by the tubings, and are run using the touchdown string equipped with knock-off valve, standpipe and hydraulic installation tool, the later by the collet engages the internal groove in the external tubular element with fixing of the landing depth levelled up by the standpipe, and weight using the dynamometer. By the second technique on the tubing in the production string with the definite speed the second block of the well equipment is run, it contains block of flows regulation and fluids metering with unions of the tubular elements of the extendable pipe connection, coupling of communication cable entry with cable connector and centrifugal pump with variable frequency drive, connected with the power cable and equipped with the remote control system, till complete connection of the extendable pipe connection. Tubing string by the adjustable branch is tightly connected with the chuck plate of the wellhead assembly, ends of both cables pass through the cable entry of the chuck plate, and the later is secured on the flange of the production string. The cables are sealed in the cable entry of the chuck plate, and are connected to the power supply unit and control panel. Tightness of the packers seating is checked by the liquid static level decreasing in the above packer space of the electric circulating pump under monitoring using the pressure gauge. Speed change of the electric circulating pump by means of the variable frequency drive and by valves position of the block of flows regulation and fluids metering the well is set to the work operation mode under control of the remote control system.
EFFECT: increased reliability of operation of dually-completed wells and reduced time of commissioning.
