METHOD OF DEVELOPMENT OF OIL-GAS DEPOSITS

摘要

FIELD: development of oil-gas deposits. SUBSTANCE: method includes making of cavity in formation bottom by hydraulic fracturing in compliance with formation occurrence with preliminary slotting. Cavity opening is not less than well diameter. This provides for excess of value of elastic convergence of cavity edges and sufficiency of unloading and disintegration of producing formation through its entire thickness. Cavity sizes exceed opening span including preliminary slotting without filling of cavity with filtering anticovering material. EFFECT: considerable rise in oil-gas recovery, reduced labor input and cost of operations. 3 cl, 2 dwg
