METHOD OF DEVELOPMENT OF OIL OR GAS DEPOSIT

摘要

FIELD: oil and gas industry. ^ SUBSTANCE: method consists in boring production well with vertical and horizontal boreholes, in working-off its feeding circuit beyond boundaries of which from surface there is bored at least one drain well similar to production one. Horizontal boreholes of drain and production wells are hydraulically communicated. Additional product withdrawal is performed via the drain well with involvement of additional tied horizontal boreholes of the production well at decreasing yield of product through the vertical borehole of the production well. The production well is puckered above the level of horizontal boreholes branching used as drain boreholes for the first system of drain wells and as production boreholes for united systems of drain wells. ^ EFFECT: raised withdrawal and residual extraction of gas, oil, or gas condensate stores from deposit. ^ 4 cl, 2 dwg
