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 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. In the process of oil and gas extraction and refining, drill pipe can be used many times. The choice of drill bit is very important, but the drill pipe with its matching also needs a good choice. How to choose the drill pipe with matching is not a small knowledge, not only to choose the good quality but also to choose the appropriate size. So how should the drill bit and drill pipe match?

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 is located at the bottom of the drilling.Drilling and grinding equipment or bottom hole device. The purpose of the drill pipe is to transport the drilling mud to the drill bit and to work with the drill.The heads together raise, lower or rotate the bottom hole device. Drill pipe must be able to withstand huge internal and external pressure, twisting, bending and vibration. In the process of oil and gas extraction and refining, the drill pipe can be used many times.Use.

The choice of drill bit is very important, but the drill pipe with its matching also needs a good choice, how to chooseChoosing a matching drill pipe is not a small knowledge, not only to choose good quality but also to choose the right one.Dimensions. So how should the drill bit and drill pipe match? Let's talk about it in detail:

First of all, it is necessary to pay attention to the effective matching of the taper of the drill bit and the drill pipe, and the matching length is at leastAt 25mm, please be sure to match the appropriate drill pipe according to this principle.

Secondly, the grinding chip bit of the drill bit must control the footage when it is in use, and the drill bit must be drilled.When it is slow, if it is found that the obtuse angle width at both ends of the drill bit is more than 2.5mmTo timely grinding to prevent excessive wear and tear of the drill bit, grinding time to use 46-60 silicon carbide sandThe wheels shall be polished at a line speed of not less than 18 m/s.

The last and most common mistake is that when disassembling the drill bit, it is best to use a drill unloader to unload the drill bit., be sure not to use a hammer to hit, excessive hit not only easy to cause problems with the drill bitIt is easy to cause the failure of the drilling rig.
