METHOD OF DEVELOPING SUPER-VISCOUS OIL FIELD Russian patent published in 2019 - IPC E21B43/24 E21B7/04 

FIELD: oil, gas and coke-chemical industries.

SUBSTANCE: invention relates to the oil-producing industry. Method of developing a super-viscous oil field includes drilling horizontal production wells, with the toe of a horizontal production well elevated by 1–5 m relative to the heel. Above the toe of a horizontal production well, 5–15 m of a horizontal injection well is drilled with a horizontal well length of 0.5–1.0 of the length of the horizontal well of a production well. And in terms of horizontal trunks injection and production wells perform at an angle of 45–90° to each other. Horizontal barrel of the injection well is divided by packers into two or three intervals, in each of which steam injection is carried out using equipment for simultaneous-separate injection. Uniform growth of the steam chamber is regulated by the modes of operation of each interval of a horizontal injection well. In addition to steam, liquid-like and/or gaseous chemical agents are periodically pumped. With the growth of the steam chamber, the development of reserves and the watering of the horizontal production well, the water-to-heel areas are subsequently isolated by a packer.

EFFECT: technical result is enhanced oil recovery in the super-viscous oil field.
