FIELD: oil and gas industry.SUBSTANCE: invention can be used when extracting a packer from a well. When extracting a packer from a well, casing valve is opened, tool is tensioned and liquid is pumped under packer, liquid under packer is pumped under pressure of saturation of bore-hole zone, after saturation of borehole pressure is increased to pressure of not more than permissible for production string. Liquid used is liquid with density 1.04-1.27 g/cmor formation water of said deposit. Liquid can also be a surfactant solution in formation water of said deposit or surfactant solution in water with density 1.04-1.1 g/cm.EFFECT: higher efficiency of extracting wedged packer from well.3 cl |
