The utility model provides a polluting oil layer oil well paraffin removal device is prevented to closed recirculation formula, includes: airtight circulation process and the superconductive heating device of airtight self -loopa formula. Its characterized in that: airtight circulation process's circular course is that oil well output liquid is in the production valve of production tree comes outto get into the superconductive heating device of airtight self -loopa formula through middling pressure pipeline and import valve, through output liquid import pipe entering heat exchanger, come outthrough the outlet valve from heat exchanger output liquid outlet pipe again, the sleeve valve of middling pressure pipeline and production tree gets into the sleeve pipe of oil well, give the heatingof the output liquid in the oil pipe, the oil well output liquid that is heated is together risen to the well head by the beam -pumping unit along with the new output liquid of oil well, production valve from the production tr
