The invention relates to the technical field of oil field equipment and particularly discloses a wear-proofing protection sleeve for an oil drilling rod. The wear-proofing protection sleeve comprisesa wear-proofing sleeve body and clamps. The oil drilling rod is sleeved with the wear-proofing sleeve body; the clamps are used for fixing the wear-proofing sleeve body; a horn mouth is formed in oneend of the wear-proofing sleeve body, and a circle of rotating edge is inwards arranged at the edge of the horn mouth; the wear-proofing sleeve body is constituted by a plastic body, and the plastic body is made of a polyurethane rubber material; flow channels in groove shapes are evenly formed axially in the outer circular wall face of the wear-proofing sleeve body; a metal reinforcing layer matched with the cylindrical shape of a sleeve main body is arranged in the wear-proofing sleeve body, the two ends of the reinforcing layer are connected with metal skeletons, and the outer ends of the skeletons are flush with the ends of the sleeve main body; and horn mouths opening gradually from inside to outside are formed in the two ends of the flow channels. The wear-proofing protection sleevehas the advantages that the problem that the oil drilling rod and the inner wall of a casing make contact directly, and thus the casing is worn through is solved, and the drilling efficiency is improved.
