AI Technical Summary
Technical Problem
The existing drill rods have poor wear resistance during oil drilling, resulting in large wear and easy damage, and reduce service life.
Method used
A high-strength wear-resistant drilling rod for oil drilling is designed. By opening a receiving groove on the outer wall of the drilling rod body and a rolling element and a return spring are provided in the groove. The movable block drives the rolling element to carry out elastic movement through elastic movement, reducing the friction force of the drilling rod body.
Benefits of technology
By reducing the friction of the drill rod body, the wear resistance is significantly improved, the service life is extended, and the problem of easy damage caused by poor wear resistance is solved.

Abstract
The high-strength wear-resistant drill rod for petroleum drilling comprises a drill rod body, a containing groove is formed in the outer wall of the drill rod body, a rolling body is arranged at an opening of the containing groove, a reset spring is fixedly connected to the inner wall of the containing groove, one end of the reset spring is fixedly connected with a movable block, and the other end of the reset spring is fixedly connected with the movable block. A plurality of sets of containing grooves are distributed in the outer wall of the drill rod body at equal intervals, a plurality of containing grooves are distributed in each set along the axial center line of the drill rod body at equal angles, and the diameter of the opening position of each containing groove is smaller than that of each rolling body. The movable block is conveniently driven to elastically move, and then the friction force of the drill rod body is reduced through rolling of the movable block, so that the wear resistance is improved, the problem that the drill rod is easily damaged due to a poor wear resistance effect is solved, and the service life is effectively prolonged.
