The utility model provides a composite biocoating anticorrosive oil pipe that insulates against heat, heat insulation oil pipe's base member is metal oil pipe, metal oil pipe's interior surfaces coated aerogel undercoating, the anticorrosive aerogel external coating of outer surfaces coated, the aerogel undercoating is by a spraying film forming completion of solid epoxy bottom of height and aerogel thick liquid surface course, anticorrosive aerogel external coating is accomplished by spraying film forming of solid epoxy bottom of height and anticorrosive aerogel surface course. Because gas gel coat possess extremely low coefficient of heat conductivity, almost prevent heat -conduction and the heat convection of crude oil with the wall of a well, and adopted the two coatings of inside andoutside wall, thermal -insulated effect is more obvious. Crude oil flows more than the wax precipitation temperature point before the outflow well head all the time to restrain brilliant the appearingof wax, reached anti -wax
