FIELD: oil and gas industry.
SUBSTANCE: in the method of increase of oil production comprising the injection through the production well into formation of water suspension of polyacrylamide treated by ionizing radiation, suspension is obtained by mixing of 1 weight part of powdery polyacrylamide with hydrolysis level 20-35% and with the molecular weight 14-23 million units, treated by the accelerated electrons with energy of electrons 5-10 MEV dose 3-30 kGr, with 25-150 weight parts of water with the subsequent swelling of suspension until formation of gel with the module of elasticity 5-30 KPa and conditional viscosity of gel suspension in the range 1.5-60. The invention is developed in dependent points of the invention formula.
EFFECT: improvement of efficiency of the method and simplification of well operation.
