FIELD: oil and gas industry. ^ SUBSTANCE: when realising the method, previously a structure is installed on a lifting pipe, comprising a set of running circular heaters to heat injection fluid in the inner cavity of the pipe, running circular heaters are connected by a cable with a source of power, the assembled structure is lowered into a well. Heat is transferred via holes in a lifting pipe into an inner cavity from heating elements of the running circular heaters to heat the injection fluid, with its subsequent movement in direction of a well bottom. The heated fluid via perforation holes of a casing pipe is injected into an oil bed, reducing oil viscosity in a bottom zone with its subsequent displacement in the bed. ^ EFFECT: reduced prime cost of produced oil due to lower power inputs. ^ 1 dwg |
