Claims (4)

1. The method of thermochemical treatment of the reservoir, including the injection into the treatment zone of the formation of a fuel-oxidizing composition (GOS) containing ammonium nitrate, urea, nitric acid, acetic acid and water, introducing into the zone of location (GOS) a combustion initiator, compressed in the form of tablets , followed by the development of the formation, characterized in that the powder treatment charge is added to the formation treatment zone from a solid propellant material containing ammonium perchlorate as an oxidizing agent, the charge being introduced either after Achievements of a combustible oxidizing composition and introducing a combustion initiator into it, either into a treatment zone prior to injecting a combustible oxidizing composition into it and introducing an initiator, or into a zone of a combustible oxidizing composition simultaneously with a combustion initiator, for which at least one of of the series: calcium hydride, magnesium hydride, barium hydride, titanium hydride, aluminum, when the content of the latter in the mixture of these hydrides is 10-50 wt.%, while the combustion initiator is introduced in an amount of not more than 5.0% by weight of the combustible-oxidative co Av. 2. The method according to claim 1, characterized in that GOS contains components in the following ratio, wt.%: Ammonium nitrate 30-50, urea 10-30, nitric acid 4.0-6.0, acetic acid 4.0- 6.0 and water up to 100. 3. The method according to claim 2, characterized in that not more than 10 wt.% Hydrochloric acid is additionally introduced into the fuel-oxidative composition. 4. The method according to any one of claims 1 to 3, characterized in that with the simultaneous use of a combustion initiator and a charge, the latter is placed either higher or lower, or between the initiator tablets.
