FIELD: mining industry.
SUBSTANCE: method includes mounting of packing element at lower limit of upper portion of thermo-isolated tubing pipe. Circulation pipe, performing a function of heat-exchange contour, with diesel fuel as heat carrier and following heat exhaust into atmosphere, is connected at whole length to upper portion of tubing string. Their lowering into well and support on the mouth is performed with displacement of tubing string axis relatively to well axis. Upper end of circulation pipe in summer period is connected to forcing line of heat-exchange plant, in winter period to forcing line of cooling plant. Forced circulation of diesel fuel is performed in upper portion of operation column through circulation pipes with following ascent along ring-shaped space. Mathematical formulae for calculating depth of packing element mounting, circulation pipe diameter, tubing string displacement value and diesel fuel flow are provided.
EFFECT: higher efficiency.
