FIELD: oil-and-gas industry.
SUBSTANCE: drilling of new wells or selection of drilled wells is executed. Several pumps are lowered in the well. Note here that in terrigenous or carbonate bed oil afflux to every productive well horizontal hole is predefined. Horizontal boreholes that differ in oil yield by 20% and more are selected. Pumps are lowered on parallel strings in horizontal borehole in length smaller than 300 m. Pumps are lowered on parallel strings in horizontal borehole in length over 300 m. Spacing between pumps does no 30 m. Every horizontal borehole is arbitrarily divided into three sequential sections. Pumps with output 2-10 times higher than that of pumps in section at horizontal borehole end are lowered at the central section.
EFFECT: accelerated oil extraction, uniform development, higher bed oil yield.
