FIELD: oil-and-gas production. SUBSTANCE: method includes selection of direction of drilling of inclined wells in conformity with rock geomechanical conditions of producing formation relative to the main horizontal stress and formation of releasing hollows - along the wells or disk-like round the well. Method efficiency is optimized by introduction of activating rock pillars between releasing hollows. Quantitative relations between sizes of releasing hollows, lengths and thicknesses of pillars are offered. Novelty consists in selection of direction of sinking inclined wells, type and sizes of releasing hollows and activating pillars. This selection results in elimination of stresses compressing the wellbore. EFFECT: higher productivity of inclined (including horizontal) wells. 7 cl, 6 dwg |
