UNIVERSAL SOLID-FUEL PRESSURE GENERATOR Russian patent published in 2018 - IPC E21B43/263 E21B28/00 

FIELD: oil and gas industry.

SUBSTANCE: pressure generator is a charge consisting of a set of solid fuel pellets having a cylindrical axial channel that are firmly attached to each other on lateral surfaces that are installed in the body of the device or on a geophysical cable. Laying of same type solid-fuel channel cartridge during generator assembly is produced by concentric rows around the central cartridge having a cylindrical axial channel. While the ratio of outer diameter of the central cartridge and the diameter of its channel is (2-7):1, the ratio outer diameter of same type solid cartridges to the diameter of their channel is (2-3):1, and the ratio of outer diameter of central cartridges and diameter of peripheral cartridges is (5-11):1. Gluing of cartridges is carried out on a length not more than 0.2 of the length of the cartridges from the side of both ends. In this case, the number of peripheral cartridges and their length are assigned depending on required pressure pulse, the maximum pressure and time of generator operation, that ensures its versatility when used in various structures of hull and open-body devices. Ignition of the gas generator is performed by means of electric heating element mounted in the outer row of peripheral cartridges in the area of their adhesion.

EFFECT: increased efficiency of the pressure generator.
