The invention relates to a production method of a wear-resistant and anti-corrosion inner coating oil pipe; the coating formula is: epoxy resin E 12 100, cast stone powder 90‑120, graphite 3‑5, molybdenum disulfide powder 10‑12, polyethylene powder 15‑20, dicyandiamide 2‑3.5, sebacic acid dihydrazide 1‑1.5, the production process includes oil removal Sandblasting, mixing, preheating, electrostatic spraying, curing, forming, grinding and polishing, inspection and powder recovery are eight steps. This method can significantly reduce the friction coefficient between the sucker rod and the inner wall of the tubing, and has anti-friction and anti-wear properties. Double function, can significantly improve the corrosion resistance of the inner wall of the oil pipe, has the advantages of short curing time, no change in the inner diameter of the oil pipe, good high temperature resistance, inhibition of scaling and waxing on the pipe wall, and long service life.
