| titleOfInvention | Device for thermo-implosion processing of oil wells |
| abstract | FIELD: mining; technological processes.SUBSTANCE: invention relates to devices for treatment of productive formation and can be used to increase efficiency of oil wells. Device for thermoimplosion treatment of oil wells includes air chamber with atmospheric pressure and plug consisting of coaxial adapter and body of combustible element. Adapter is equipped with internal support element dividing it into two parts, in one of parts on support element is rigidly fixed combustible element, equipped with monolithic gas-generating during combustion of composite material, consisting of mixture of ammonium nitrate granulated grade B, catalyst, combustible binder comprising, wt%: epoxy resin grade ED-20-76; plasticiser of EDOS-8 grade; agidol AF-2M – 16, and an igniter operated from an electrical spiral. Inner support element of adapter is made in form of ring rigidly fixed on its surface, at that part facing to air chamber is open, and the gas generating composite material contains potassium ferrate as a catalyst, with the following ratio of components, wt%: granular ammonium nitrate of B grade – 71.0–73.0; potassium ferrate – 1.0–3.0; combustible binder – 24.0–28.0.EFFECT: improving reliability and efficiency of device operation due to provision of its tightness and stability of combustion process of composite material with simplification of its design.1 cl, 2 dwg |
