The composition, function and importance of drilling drill pipe

Drilling drill pipe composition:
Drilling drill pipes are generally composed of multiple drill pipes. The length and number of drill pipes are determined according to the well depth and drilling conditions. Its main components include joints, pipe bodies, threads and drill pipe protective sleeves, etc. Each part has a different purpose.

1. Connector
The joint is the connection between the upper and lower parts of the drill pipe. Its main function is to connect the drill string and the bottom hole stress system. It must have the ability to withstand pressure and wear.

2. Pipe body

The pipe body is the main part of the drill pipe. It is composed of multiple sections of steel or alloy pipes of the same length. There is a certain hollow inside, which can be used to transfer liquids and samples.

3. Thread
Threads are the core part of drill pipe connections. They are generally used to connect pipe bodies and joints and must have high strength and corrosion resistance.

4. Drill pipe protective sleeve
The drill pipe protective sleeve is a removable protective sleeve that is usually installed at the connecting thread of the drill pipe to protect the threaded part from wear and damage.

The functions of drilling drill pipe:
Drilling drill pipe is a multi-segmented tool on the drilling platform that hangs down with the drill string. It is mainly used to lower the drill bit and other materials to the bottom of the well, and at the same time bring away the oil, natural gas, water and other substances at the bottom of the well. Come up. In drilling operations, drilling drill pipe is one of the indispensable tools because it can complete the following important tasks:

1. Provide necessary strength and stiffness
Drilling drill pipe needs to bear the weight of tools such as drill bits and the torsional and lateral forces generated during drilling. Therefore, it needs to have a certain strength and stiffness to ensure the stability and safety of drilling.

2. Transfer power and torque
Drilling drill pipe not only needs to bear the weight of tools such as drill bits, but also needs to transfer the power and torque generated by the drilling rig to ensure smooth drilling.

3. Transfer fluids and samples
The inner hollow of the drilling drill pipe can be used to transport fluids such as drilling fluids and fracturing fluids, as well as materials such as rock and soil samples, so as to facilitate timely collection and analysis of geological exploration work.

Importance of Drilling Drill Pipe:
Drilling drill pipe plays a very important role in drilling operations. It is not only the core component of the entire drilling system, but also a necessary tool to complete drilling tasks. In addition, drilling drill pipe also has the following important functions:

1. Ensure drilling safety and stability
Drilling drill pipe needs to bear the weight and torsion force of drill bits and other tools, and must have a certain strength and stiffness to ensure the safety and stability of drilling.

2. Collect geological samples and fluids
The inner hollow of the drilling rod can be used to transport rock, soil and other samples and liquids, and can provide reliable support for drilling geological exploration work.

3. Solve drilling problems
The tool boxes and equipment provided by the drilling pipe and drilling platform can deal with various drilling problems, such as the drill bit getting stuck in the drilling hole, formation collapse, etc.

To sum up, drilling drill pipe plays a very important role in drilling operations. It can not only ensure the safety and stability of drilling, but also collect geological samples and fluids to solve drilling problems. Therefore, in drilling operations, the role of drilling drill pipe is irreplaceable.
