METHOD FOR GAS-DYNAMIC PROCESSING OF FORMATION AND DEVICE FOR REALIZATION OF SAID METHOD Russian patent published in 2007 - IPC E21B43/263 

FIELD: oil extractive industry.

SUBSTANCE: method includes assembly of unpackaged section charge by letting composite bar through central channel of charge sections with developed surface, contracting and packing of charge sections tightly with each other, positioning of lower sections of gas flow draining disperser charge, forming during combustion of charge sections, with through apertures, lowering and installing of charge in processing interval, combustion of charge sections, accompanied by temperature increase and generation of hot gunpowder gases. In accordance to invention, additional gas stream draining disperser is located above charge sections assembled higher. Dispersers are made so that cylindrical parts are added to them without through apertures, which are located on the sides of assembled charge sections. Central channel of charge sections and adjacent parts of internal hollows of dispersers without through apertures are filled with substance, which prevents charge sections heating above the temperature of their ignition. Sections of internal hollows of dispersers with through apertures are filled with viscous inert substance, which in case of combustion of charge sections and creation of increased pressure in internal charge hollow exits disperser apertures first and creates a closed volume in well in processing interval, separating formation processing interval from whole borehole - packer is created. Invention includes a formation processing device with an additional disperser.

EFFECT: possible operation in deep wells on thermal deposits.
