FIELD: oil and gas industry, particularly methods or apparatus for obtaining oil from wells.
SUBSTANCE: device has two charges of solid fuel including a set of cylindrical channel explosive cartridges and components for their assemblage. Cartridges are vertically placed one on another and cartridge edges are connected one to another by combustible polymeric collars. Installed in upper device part is slow-burning charge with end face burning formed of gas-generation fuel, which creates high temperature products of combustion. Arranged in low device part is fast-burning fuel charge extracting hydrogen chloride during combustion thereof. Hydrogen chloride quantity is enough to form hydrochloric acid in amount of 20% of charge weight. Charges are ignited by igniter arranged on upper end of slow-burning charge by applying electric impulses from well head.
EFFECT: increased operational temperature and time range, simplified structure and production technology.
