FIELD: oil industry.SUBSTANCE: invention relates to oil industry. 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 horizontal bores of upper injection wells is shorter than horizontal bores of lower production wells, pumping steam through the top delivery wells and selection of production through the lower production wells, at the sequential arrangement of horizontal bores of wells located by their beginnings to each other in dome part of the deposit, the upper wells carry out shorter on 10-40 % from lower wells, part of wells from day surface to horizontal shafts carry out as inclined, inclined shafts equipped with upsetting column, cement annular space above a horizontal shaft, a mode of steam pumping through upper injection wells is prescribed in an amount of 50-120 t/day, and product of extraction mode through lower production wells is prescribed in an amount of 50-150 t/day.EFFECT: technical result - increase of the deposit oil recovery factor.1 cl, 1 dwg, 3 ex |
