FIELD: oil and gas extractive industry, namely, technology for increasing efficiency of extraction of water-oil zone of oil deposit.
SUBSTANCE: in accordance to method, on one set of ends of all extraction elements close to roof of productive bed extracting horizontal well is drilled, perpendicular to external water-oil contact. As force well, vertical well is used, which is positioned on opposite ends of all extraction elements in water-oil zone close to external boundary of water-oil contact or immediately behind it with opening of whole water-bearing bed. Force wells should be positioned at such distance from product wells, so that oil is pushed towards the well by bed water at bed temperature. In case of significant porosity of productive bed, product borehole intersects layers from roof to last argillaceous or dense layer in direction to pure oil zone.
EFFECT: increased efficiency of extraction of oil-water zone of oil deposit using large scale mathematical experiments.
