PDC Different Hole Diameters Drilling Bits For Water Well Drilling

Product Introduction

The development of PDC drill bit technology and materials has not only achieved breakthroughs, but also undergone significant changes in its usage. It can be used not only in highly corrosive bottom layers but also in hard bottom layers. After all, the original product may not be able to be used in harder interlayers due to low product quality, which is prone to damage. If the technology is improved, it can also be used in hard rock formations, And it is increasingly recognized by people. Nowadays, when purchasing PDC drill bits, it is possible to learn about the products produced by relevant enterprises. Choosing products produced by professional manufacturers is more reliable in quality, and the quality of the products has been well upgraded and improved. Not only does it have a longer lifespan, but it also has better durability.

 PDC combination drill bits have the following advantages:

1, Overall advantages:

The PDC combination drill bit adopts a combination design of multiple polycrystalline drill bits, fully leveraging their respective advantages and improving drilling efficiency and quality.

2, Advantage 1: High efficiency

PDC combination drill bits have high drilling speed and efficiency. Due to the use of multiple polycrystalline drill bits, each bit can fully utilize its drilling ability, thereby improving the overall drilling speed. In addition, PDC combination drill bits can also select suitable drill bit combinations based on the characteristics of different formations, further improving drilling efficiency.

3, Advantage 2: Good drilling quality

PDC combination drill bits have good cutting ability and stability, and can effectively cope with drilling difficulties in various formations. The cutting teeth of polycrystalline drill bits have high hardness and wear resistance, which can maintain a long service life in complex formations. In addition, PDC combination drill bits can also be replaced and adjusted as needed to meet the requirements of different formations, thereby improving drilling quality.

4, Advantage 3: Reduce costs

The use of PDC combination drill bits can reduce drilling costs. Due to the high efficiency and good drilling quality of PDC combination drill bits, drilling time and frequency can be reduced, thereby reducing drilling costs. In addition, the PDC combination drill has a longer service life, which can reduce the frequency of replacing drill bits and further reduce maintenance costs.

In summary, PDC combination drill bits have the advantages of high efficiency, good drilling quality, and cost reduction. By fully utilizing the characteristics of multiple polycrystalline drill bits, PDC combination drill bits can improve drilling efficiency and quality, reduce drilling costs, and are a drilling tool worth promoting and applying.

The structural characteristics of PDC drill bits include the drill bit body, PDC cutting teeth, and nozzle, which are divided into two series according to their different structures and manufacturing processes: steel body and matrix body.

The upper part of the PDC drill bit body is made of steel, and the lower part is made of tungsten carbide wear-resistant alloy matrix, which is manufactured using powder metallurgy sintering technology. Weld the PDC cutting teeth onto the reserved grooves of the tire body using low-temperature solder. Tungsten carbide matrix has high hardness and erosion resistance, so PDC drill bits with matrix have a long service life and high drilling depth, and are currently widely used.

The entire drill body of the steel PDC drill bit is made of medium carbon steel material and processed into shape using mechanical manufacturing technology. Drill holes on the working surface of the drill bit and secure the PDC cutting teeth to the crown of the drill bit in a press fit manner. The crown of the drill bit is treated with surface hardening technology (spraying tungsten carbide wear-resistant layer, carburizing, etc.) to enhance its erosion resistance. The main advantage of this type of drill bit is its simple manufacturing process; The disadvantage is that the drill bit body is not resistant to erosion, and the cutting teeth are difficult to secure, so it is currently less widely used.
