UNIVERSAL SOLID-FUEL WELL PRESSURE GENERATOR Russian patent published in 2016 - IPC E21B43/263 

FIELD: mining.

SUBSTANCE: invention relates to solid-fuel pressure generators for intensification of oil and gas production, used in complex well treatment in pulse frame and frameless devices. Pressure generator consists of a set of solid-fuel blocks, rigidly attached to each other along side surfaces, installed in device frame or on a cable. Laying of single-type solid-fuel pellets in assembly of generator is carried out in concentric rows around central block, having a cylindrical axial channel. Ratio of outer diameter of central block and diameter of peripheral blocks is equal to (2.2-5.5):1. Gluing of blocks is performed on length of 0.065-0.1 of length of blocks on side of both ends. Number of peripheral blocks and their length is assigned depending on required pressure pulse, maximum pressure and time of operation of generator, that provides its versatility when used in different structures of frame and frameless pulse generator devices. Ignition of gas generator is performed by means of electric heating element, built into one of peripheral blocks of external row in area of gluing blocks.

EFFECT: higher efficiency of pressure generator.
