FIELD: gas and oil production.
SUBSTANCE: procedure consists in lowering heating device for recovered fluid into production string. The device corresponds to a process string with a back valve on an end lowered at depth below beginning of paraffin deposits. Heat carrier is pumped into the string during operation of the well by introducing heat carrier into a flow of recovered fluid till at wellhead it reaches temperature as high, as temperature of paraffin melting. Heat carrier is pumped cyclically or continuously. At cyclic heat carrier pumping beginning of each cycle is determined by rise of pressure at intake of a pump and reduction of well yield in comparison with set values of pressure and yield at operation of well under a process mode.
EFFECT: raised efficiency, simplified process of procedure.
