FIELD: oil and gas production.
SUBSTANCE: procedure consists in implementation of hydro-jack block mounted of wellhead after disassembly of production tree to main gate, whereupon main gate is removed from tubing string head by means of hydro-jack bock. Further, the hydro-jack block is connected to flow string; the flow string is stretched; a control head is connected to the flow string; the control head and the suspended flow string are installed in the production well; and the tubing string head is dismantled.
EFFECT: reduced labour intensiveness and increased efficiency, also reduced idle time of well and elimination of unfavourable results of operation related to production horizon, absence of leaks of well medium to atmosphere.
