FIELD: mining. ^ SUBSTANCE: invention can be implemented for prevention of loss of fluidity of oil containing pyrobitumens and resins and for prevention of paraffin and hydrated plugs generation in pump-compressor pipes (PCP) of wells. Production of a well (WP) is heated continuously in M points of a well borehole by means of heating pipes of separate heated sections (HS) of PCP with heating elements installed on an exterior surface of the pipe HS. Temperature is measured on the surface of the pipe of each HS on its upper end. Heating is commenced immediately after installation of PCP column with HS into the well and after start-up of the well. Heating is turned off and electric power of electric feeding block channel of j-point is decreased, where j=1,2...,M, at reaching maximum preset value. Heating at j-point of heating is turned on when the measured temperature on the surface of the HS of the pipe reaches the preset value. Also the preset temperature value is chosen so that up to the next heating point or to a well head HS would carry the temperature by 5-10 degrees exceeding the temperature which can cause loss of fluidity of HS having pyrobitumens and resins in its composition or when commencement of paraffin generating and settling on interior walls of the pipe can occur. ^ EFFECT: increased yield of well production due to prevention of oil fluidity loss and due to prevention of plug generating and more expanded field of application. ^ 2 cl, 3 dwg
