The invention discloses an anticorrosion wear-resistant coated heat-insulation oil pipe composed of an oil pipe body, an anticorrosion wear-resistant layer inside the oil-pipe body, a heat insulation layer outside the oil pipe body, and an anticorrosion protecting layer outside the heat insulation layer. An inner pipe is fixedly nested in the oil pipe body, an outer heat insulation layer uniformly wraps the outer wall of the middle section of the oil pipe body, and an outer anticorrosion protecting layer wraps the outer wall of the heat insulation layer. Another heat insulation layer wraps a connecting hoop and an upper operating section and a lower operating section which are connected with the connecting hoop of the oil pipe body, and a heat-insulation layer protecting steel casing is mounted outside the referred heat insulation layer. By the anticorrosion wear-resistant coated heat-insulation oil pipe, loss of own temperature of crude oil when flowing from a well bottom to a wellhead is effectively reduced, and flow state of the crude oil in a wellhole is improved. The problems about an eccentric wear of rod pipes of the oil pipe, corrosion resistance inside the oil pipe, scaling, wax precipitation, corrosion resistance outside the oil pipe are solved, friction resistance among the rod pipes of a rod pumped well is reduced, finally, energy is saved, emission is reduced, damages to the rod pipes are reduced, downhole operation load is reduced, and exploration cost of oil is greatly reduced.
