CHARGE FOR POWDER PRESSURE GENERATOR (OPTIONS) Russian patent published in 2021 - IPC E21B43/263 

FIELD: oil industry.

SUBSTANCE: invention relates to the field of the oil industry, namely to powder pressure generators intended for thermobarochemical treatment of a productive formation in order to intensify oil and gas production. The charge represents the same type of tubes of artillery powder with a central cylindrical channel, assembled in concentric rows tightly to each other around the central removable equipment to obtain a cylindrical axial channel. The tubes are firmly attached to each other into a single powder charge by gluing them along the entire length or along both ends of the charge using a solvent. The igniting charge is a single-type tube of artillery powder with a central cylindrical channel, assembled in concentric rows tightly to each other around the central removable tooling to obtain a cylindrical axial channel. The tubes are firmly attached to each other into a single powder charge by gluing them along the entire length or along both ends of the charge using a solvent. In the middle row of the igniting charge between the tubes of artillery powder along the axis of the charge, there are 1 to 4 equidistant ignition devices with electric heating elements.

EFFECT: stability of the ignition, high completeness of combustion and reduced burning time of the charge.
