FIELD: oil production. SUBSTANCE: invention can also be used to raise efficiency of development of oil fields thanks to equalization of profile of acceptance of injection wells and insulation of water inflow in production wells. Gel-forming polymer material to equalize profile of acceptance and water insulation of wells based on water-soluble polymers of acryl series radiation-treated in solid phase has polymers treated by pulse ionizing radiation with absorption dose of 0.5-7.0 Mrad and pulse length between 10-8-10-4 s. It should be additionally treated with additives of plasticizing agents. Process of production of gel-forming polymer material for equalization of profile of acceptance and water insulation of wells consists in irradiation of powder of water-soluble polymer of acryl series by ionizing radiation which secures that irradiation is conducted by pulse ionizing radiation with pulse length 10-8-10-4 s and pulse power 1010-5•1014 rad/s till absorption dose of 0.5-7.0 Mrad is obtained. Irradiation is conducted by pulse beam of accelerated electrons with kinetic energy not less than 0.3 MeV. Installation for production of gel-forming polymer material to equalize profile of acceptance and water insulation of wells has source of ionizing radiation and device to feed polymer powder into irradiation chamber. Source of ionizing radiation comes in the form of heavy-current pulse electron accelerator with extraction of beam into irradiation chamber. Device to feed polymer powder is realized on principle of uninterrupted supply of powder into irradiation chamber and is fitted with governor controlling rate of flow of powder through irradiation chamber. Target-converter transforming electron beam into braking roentgen radiation is installed across outlet of electron accelerator. EFFECT: improved rheological properties and stability, diminished radiation hazard for personnel and environment. 6 cl, 2 dwg, 1 tbl
