METHOD FOR DEVELOPMENT OF OIL FIELD Russian patent published in 1994 - IPC

FIELD: oil production. SUBSTANCE: field with porous-fractured reservoir before injection of oxidizer is developed under conditions of dissolved gas drive up to possibility of filtration of gaseous oxidizer in low-permeable zones with flow-rate required to maintain stable burning process in formation. Field is developed under conditions of dissolved gas drive up to attainment of relative phase permeability of low-permeable zones determined by formula. Additionally, periodically water is injected into formation in the amount required for maintaining pressure gradients ensuring filtration of gaseous oxidizer in low-permeable zones. After break-through of gaseous oxidizer into producing well, injected into formation alternately with gaseous oxidizer is water in the amount equalling the volume of formation fractures. Before injection of oxidizer fed into formation is heat carrier in amount equalling 0.5-5.0 of volume of fractures of reservoir. EFFECT: higher efficiency. 5 cl
