METHOD FOR DEVELOPMENT OF HIGH-VISCOSITY OIL DEPOSIT Russian patent published in 2016 - IPC E21B43/24 E21B7/04 

FIELD: oil industry.

SUBSTANCE: invention relates to oil industry and can be used in development of high-viscosity oil. In the development method of high-viscosity oil deposit, which involves arrangement of horizontal bores of production and injection wells in parallel and serial, design of upper injection wells is shorter than the lower production wells, pumping steam through upper injection well and extraction of products through lower production wells, with sequential arrangement of horizontal boreholes of wells located by their beginnings to each other in dome part of the deposit, the upper well is shorter then lower well on 10-40 %, at the same time the parts of wells above horizontal shafts are inclined, and pumping steam through injection wells is carried out through inclined and horizontal part of wells.

EFFECT: technical result - increase of the deposit oil recovery factor.
