The drill pipe is a rod connected in the drilling tool to transmit power. The drill pipe is a steel pipe with a thread at the tail, which is used to connect the surface equipment of the drilling rig and the drilling equipment or bottom hole device at the bottom of the drilling. The usual components of the drill pipe are: drill bit, drill collar, drill pipe, stabilizer, special joint and kelly pipe. The purpose of the drill pipe is to carry drilling mud to the drill bit and raise, lower or rotate the bottom hole device together with the drill bit. The drill pipe must be able to withstand huge internal and external pressure, distortion, bending and vibration, so the wear of the drill pipe is a very serious problem. When the drill pipe is worn to a certain extent, it should be replaced with a new one.

When the drill pipe is worn to a certain extent, it should be replaced with a new one.
So let's take a look at some suggestions to reduce the wear of the drill string:
1, research and development of high-quality materials drill pipe to use high-strength materials, the selection of lightweight aluminum alloy and other materials as the drill pipe material; improve the processing technology, do a good job of heat treatment, so that the internal structure of the drill pipe more refined and perfect.
2. Control the verticality of the drilling. If the verticality of the drilling is high, the contact surface between the drill string and the hole wall will be reduced accordingly, and the rotation around the axis will increase, thereby reducing the friction between the drill string and the hole wall.
3, improve the use of solid-free drilling fluid drilling fluid, reduce the viscosity and density of drilling fluid, in order to reduce the erosion and wear of the drill string; improve the PH value, inhibit the corrosion of acid gas on the drill string; use oxygen scavenger, reduce the oxidation of the drill string corrosion.
The use of drill pipe is extensive. The drill pipe must be able to withstand huge internal and external pressure, distortion, bending and vibration. In the process of oil and gas extraction and refining, drill pipe can be used many times. nantong hengtong machinery manufacturing co., ltd. is a professional committed to the production of rotary drilling rig drill pipe, drilling tools of enterprises. The company has a variety of advanced production, processing, testing equipment, strong technical force, strict scientific management, excellent product quality, good after-sales service, has won the trust of users.
