A 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 and grinding 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 large torques, twists, bends and vibrations during rotation. During the drilling process, the drill pipe can be used multiple times. The operation procedures for drill pipes are as follows: 1. Hole position. Do not form the operation of the drill pipe, but be careful not to "don't" the drill pipe. 2. Release the drill. Under the action of the gravity of the drill pipe and the drilling tool, the friction force of the hole wall and the mud are overcome.

The drill pipe must be able to withstand large torques, twists, bends and vibrations during rotation. During the drilling process, the drill pipe can be used multiple times.
The operating procedures for drill pipes are as follows:
1. Pair position. Do not form the operation of the drill pipe, but be careful not to "don't" the drill pipe.
2. Release the drill. Under the action of the gravity of the drill pipe and the drilling tool, the process of overcoming the friction force of the hole wall and the mud buoyancy to achieve the extension of the drill pipe is called drilling. The correct drilling sequence is: the outer rod is lowered into place, and the adjacent inner rod starts to extend from the inner of the outer rod, from the outside to the inside, one by one.
3, drilling, pressure, with appropriate rotation speed forward drilling.
4. Complete bottom unloading. Be careful not to "don't" drill pipe when unloading and closing. Note: when using friction drill pipe for drilling, each time includes the five sequences of "hole location, drilling, drilling, lifting, unloading and bottom. It is necessary to "do not fall into order", "do not disorderly", "do not arbitrarily increase the order".
Drill pipe plays an important role in the drilling process. It transmits the torque of the drilling rig to the drill bit to realize drilling. In the drilling, the drill pipe is subjected to a very complex load, almost at the same time under the tension, compression, torsion, bending and other stress, the quality of the drill pipe plays a vital role in the drilling work. We Shandong Yikuang Drilling Technology Co., Ltd. specializes in the production of rotary drilling rigs, drilling tools, etc., with reliable product quality and stable performance. It has become a high-quality enterprise in the drill pipe and drilling tool industry. Warmly welcome new and old customers to negotiate cooperation!
