The invention discloses a treatment method for improving the surface performance of a conveying pipe in petroleum engineering and relates to the technical field of petroleum engineering equipment. Thetreatment method comprises the following steps that (1), ultrasonic oil removing, specifically, the conveying pipe is placed inside an oil removing tank, and ultrasonic field performs oil removing onthe conveying pipe in combination with an oil removing agent; (2), high-pressure water washing, specifically, washing treatment is performed utilizing high-pressure water; (3), electropolishing, specifically, the conveying pipe is put into an electrolytic tank to be subjected to electrolytic polishing treatment; (4), film plating, specifically, the conveying pipe is placed inside a film evaporation plating machine, then rare earth electrothermal coating is added into the film evaporation plating machine, then the film evaporation plating machine is internally vacuumized and applied high-voltage direct current electric field arc discharge, and then ultraviolet light solidification is performed after a leveling rare earth electrothermal film layer is heated. By means of the treatment methodfor improving the surface performance of the conveying pipe in petroleum engineering, the surface of the conveying pipe for petroleum engineering is treated, the abrasive resistance and corrosion resistance of the conveying pipe are improved, the treated conveying pipe has quite good high-temperature resistance and is strong in anti-aging performance and high in mechanical strength, the service life is effectively prolonged, and the treatment method for improving the surface performance of the conveying pipe in petroleum engineering has quite good promotion value.
