METHOD FOR PACKER GAS WELL KILLING

FIELD: oil and gas production, particularly killing of gas and gas condensate well equipped in accordance with packer scheme before overhaul of wells drilled to thick productive reservoir or drilled in several reservoirs simultaneously. ^ SUBSTANCE: method involves lowering flexible pipe in well; injecting killing liquid via flexible pipe inside well, wherein killing liquid has volume equal to production tubing volume; simultaneously bleeding air into flare line via newly-created annular space between production tubing and flexible pipe lowered in the tubing; sealing flexible pipe interior; serially injecting blocking solution in annular space so that the blocking solution fills the whole perforation interval and killing liquid having volume equal to sum of annular space volume and blocking solution volume; forcing blocking solution in well bottom zone; removing flexible pipe from well; opening circulation valve, for instance by wireline operations; filling well hole annuity with killing liquid; leaving well as it is for technological time-delay; bleeding gas caps accumulated during technological time-delay from tubing and hole annuities by providing flow circulation via opened circulation valve. As well is drilled in thick reservoir or in several reservoirs flexible pipe is lowered up to lower orifices of perforation interval and blocking solution is forced in reservoir along with flexible pipe lifting within perforation interval. ^ EFFECT: increased reliability of gas and gas-condensate packing well killing.
