It is a kind of drilling tool made of integral casting or forging process, with extremely high strength and rigidity. It is suitable for deep hole drilling, complex formation drilling, and drilling operations requiring high torque transmission. The surface of the integral heavy duty drill pipe is specially treated to provide excellent wear and corrosion resistance.
Suitable for drilling in soft and medium hardness formations. The spiral groove design can increase the friction between the drill pipe and the hole wall and improve the drilling efficiency. At the same time, this kind of drill pipe also has good strength and rigidity, can withstand large drilling pressure and torque.
A welding process is used to connect multiple drill pipe segments. It is suitable for long distance drilling, complex formation drilling, and drilling operations requiring high flexibility. It has high strength, high rigidity and good corrosion resistance, which can meet the needs of drilling in various complex geological conditions.
When connecting the drill pipe with the drill bit and drill tool, ensure that the connection part is clean and free of impurities.
Use special connection tools or equipment to connect according to the specified torque to ensure that the connection is firm and reliable.
Before starting the rig, ensure that the drill pipe is properly installed and secured.
Gradually increase the pressure and speed of the rig to avoid damage to the drill pipe caused by sudden increase in load.
During the drilling process, we should pay close attention to the working state of the drill pipe, and stop the machine for inspection in time if there is any abnormality.
After drilling, the drill pipe should be removed from the drill hole, and cleaned and maintained.
Check the drill pipe and its connecting parts for wear and tear, and replace or repair them if necessary.
In the process of drilling, safety operation rules should be strictly observed to ensure the safety of personnel and equipment.
The heavy weight drill pipe should avoid collision with hard objects during use, so as not to damage the surface or internal structure of the drill pipe.
