What are the categories of oil drill pipes?

Posted by BAOWI STEEL MANUFACTURING CO.,LTD on March 28th, 2024

Oil drill pipe is indispensable in the drilling process of Fu oil field and is mainly used for drilling, coring, oil testing and other operations. According to the material, structure and use of drill pipe, it can be divided into the following categories:

1.Steel pipe drill pipe

Steel pipe drill pipe is a drill pipe made of high-strength seamless steel pipe, which is mainly suitable for conventional drilling operations. It is characterized by its simple structure and easy maintenance and replacement. However, due to the limited strength of the steel pipe, it cannot be suitable for deeper drilling operations.

2. Rotary drill pipe

The characteristic of the rotary sticky rod is that it is composed of multiple drill pipes and is equipped with a turntable to control the rotation of the drill pipes at the wellhead. This drill pipe is suitable for complex operations such as deep wells and directional wells, and has a high degree of control performance. However, due to the complex structure, maintenance is difficult.

3.Non-pluggable drill pipe

Non-pluggable drill pipes are composed of multiple sections of seamless steel pipes, and connecting rods are used to connect the various parts together. The characteristics of this drill pipe are that it can be used for relatively deep drilling and has good durability. However, due to the existence of the connecting rod, it is not conducive to the seamless connection of the work flow, and requires careful operation to achieve the ideal effect.

4. Spiral drill pipe

Spiral drill pipe is made of multi-section drill pipes seamlessly connected using a spiral design. It has the characteristics of high strength, high durability, and resistance to twisting moments. It can be applied to complex working conditions such as deep wells and high-pressure wells, and has efficient and stable working performance. However, due to the difficulty of manufacturing, the cost is high.

In short, various oil drill pipes have their own scope of application, advantages and disadvantages. The continuous updating and innovation of oil drill pipe materials and processes will provide more efficient, safe and stable tools for the growing oil field development industry.
