FIELD: oil and gas production.
SUBSTANCE: procedure consists in determination of pays divided with impermeable clay interlayers, and in driving main horizontal boreholes in middle of pay. Above and below the pay there are drilled horizontal laterals along producing interlayers. According to the invention impermeable clay interlayers are shut off with profile shutters. Also, hydraulic or acid break is carried out in each horizontal bore of producers before their bringing into service. Hydraulic break in terrigenous reservoirs is performed successively downright, while hydraulic acid break in carbonate reservoirs is carried out successively bottom-up.
EFFECT: raised efficiency of development due to increased sweep of reservoirs, reduced expenditures for construction and simultaneous extraction of stock from several interlayers.
