The overall weighted drill pipe is made of AISI4145h alloy steel, and the material has undergone all heat treatment. All physical properties comply with the newly issued API specification 7.Weighted drill pipe is a transitional drill string section between ordinary drill pipes and drill collars. It can effectively alleviate stress concentration in the transitional section between drill collars and drill pipes, provide drilling pressure, and effectively reduce the connection area and outer diameter wear rate between drill pipes and wellbore. There is a thickened section in the middle of the drill pipe, and the surface of the joint and the thickened section in the middle are welded with hard alloy to form a wear-resistant band, which can effectively protect the drill pipe from wear. Weighted drill rods can replace drill collars to solve a series of problems that occur in vertical drilling in softer geological structures. Its advantages include:

1. Reduce torque for high-speed drilling and deep well drilling
2. Drive the drill collar portion of the drill string in less time
3. Reduce fatigue damage to tool joints
4. Easy to operate and operate the drill string
5. Can help maintain the direction of directional wells
