DEVICE FOR THERMOBAROCHEMICAL TREATMENT OF WELLS AND METHODS OF ITS APPLICATION Russian patent published in 2023 - IPC E21B43/16 E21B43/25 

FIELD: oil and gas industry.

SUBSTANCE: invention can be used in the treatment of the bottomhole formation zone in order to restore the filtration of the bottomhole formation zone and increase the productivity of the well. A device for thermobarochemical treatment of wells is claimed, containing a perforated pipe with a plug in the lower part, lowered on a pipe string into the well, and a thermal gas generator installed in it and made of a solid fuel combustible composition in a tubular container with an ignition unit. At the same time, the ignition unit comprises an igniter made in the form of an electric heating element that interacts with the combustible composition and is located in its lower part, a container with a current source and an electrical contact unit, consisting of at least one pair of normally open contacts closed under the action of an axial force. A method for thermobarochemical treatment of wells is also claimed.

EFFECT: simplification of the technology of influencing the bottomhole formation zone due to the exclusion of cable technology while ensuring high work productivity.
