FIELD: oil-and-gas industry. ^ SUBSTANCE: invention related to oil-and-gas industry and can be used for water inflow into well limitation methods. According to the method execute high viscosity oil and cement heated mixture pumping via thermal insulated pipes, driving with low viscous oil and process ageing. According to the invention kill the well with well killing fluid, execute works until well specific intake capacity value is equal 0.5-3.0 m3/(hMPa), pump into the well not less then 8 m3, with density equal well killing fluid density. Execute pumping though thermal insulated pumps of the high viscosity oil and cement heated mixture with consumption rate 2-10 m3/hour. ^ EFFECT: production wells water inflow insulation efficiency increase. ^ 1 ex |
