FIELD: oil and gas industry.
SUBSTANCE: method for accumulating cold in the formation involves the use of a two-tube arrangement in a dual horizontal well, lowering of a first lift pipe with packer installation for separating the annulus and production of oil, lowering a second lift pipe of smaller diameter. Coolant is circulated by means of injection into the second lift pipe and lifting along the annulus. In this case, the formation is cooled simultaneously with production of oil from the well, as a result the conditions for keeping hydrates at the boundary of gas-oil contact are provided.
EFFECT: increased oil recovery of oil-gas condensate fields due to presence of hydrate barrier at the boundary of gas-oil contact.
