FIELD: oil production industry. SUBSTANCE: method can be used for isolation of water inflow, absorbing zone, and for shut-off of well bed in injection and producing wells. According to method, introduced into well is isolating component. Generator of gases is installed in zone of well to be treated. Gas generator is actuated. Mixed inside generator body is gaseous medium produced due to initiation of generator and isolating component. This resulted in producing thermodiffusion isolating mixture which is introduced into isolation zone by pressure of gaseous medium. Pressure of gaseous medium is not higher than pressure of well bed fracturing. Used in function of working agent of gas generator is powder charge. Isolating component is included in composition of powder charge. EFFECT: higher efficiency. 7 cl
