Beschreibung
Zusammenfassung:	FIELD: oil and gas extractive industry. ^ SUBSTANCE: method includes placement of mixture of fuel and oxidizer in the well, initiation of reaction of fuel oxidizing by means of heat from well heater and supporting of reaction of oxidizing in mode of stable burning of mixture without its detonation. Ratio of oxidizer to fuel in mixture is derived on basis of condition of full burning out of fuel with maximal gas generation, at zero, at least, oxygen balance. Gas generation dynamics is given as linear or close to linear relation of changing of volume of gas generated during burning in time, enough for opening natural vertical cracks of productive bed. ^ EFFECT: higher effectiveness of method due to making draining profile even along whole thickness of productive bed while decreasing energy consumption and increasing safety of operations. ^ 13 cl
