Abbreviation for polycrystalline diamond compact drill bit. It is a drilling tool commonly used in the geological drilling industry.

Fold and edit this paragraph PDC drill bit classification

Folding material classification

⒈ Matrix PDC drill

Matrix-type diamond compact (PDC) drill is a cutting-type drill in which the diamond compact is welded to the drill matrix by brazing. The matrix drill bit is sintered with tungsten carbide powder, brazed on the tungsten carbide matrix with artificial polycrystalline diamond composite sheet, and used natural diamond to keep the diameter.

⒉ Steel body PDC drill

Steel body PDC bits are machined from nickel, chromium and molybdenum alloys. After heat treatment, drill holes on the drill bit body, press the synthetic polycrystalline diamond composite sheet into (tight fit) the drill bit body, and use columnar tungsten carbide to maintain the diameter.

Folding applicable industry classification

⒈Compound drill bit for geological exploration

The composite drill bit mainly used for geological exploration and exploration is suitable for soft to medium hard rock layers. Now some manufacturers have newly developed new composite chips that can be applied to ten-grade hardness rock layers.

⒉ Coal field drilling adopts composite drill bit

It is mainly used for coal seam drilling and mining in coal mines. Generally speaking, the rock formation in the coal field is relatively soft, and the composite drill bits are widely used, such as bolt bits, tri-wing bits and so on.

⒊Compound drill bit for petroleum exploration

It is mainly used for drilling in oil and gas fields. At present, the oilfield composite drill bit is the most expensive and the most demanding among all the composite drill bits. It can be said that it is a noble in the composite drill.

Fold edit the development status of this paragraph

The quality and type of PDC cutters has changed dramatically in recent years. If you compare the teeth of the 1980s with today's teeth, the difference is considerable. Today's cutters have much better quality performance due to changes in mixing and manufacturing processes, making the drill bit more resistant to erosion and impact.

Engineers also optimized the interface between the tungsten carbide substrate and synthetic diamond to improve the toughness of the cutting teeth. Innovations in the layered diamond process have also been used to improve the abrasion resistance and thermal stability of the product.

In addition to the development of materials and manufacturing processes, PDC products have also achieved major breakthroughs in tooth design technology and tooth placement. Now, PDC products can be used in areas where they could not be used before, such as harder, more abrasive and more variable formations. This expansion into new areas has had a major impact on the balance between diamond (fixed cutter) bits and roller cone bits.

Initially, PDC bits could only be used in soft shale formations because hard interlayers would damage the bits. However, due to the emergence of new technologies and structural changes, PDC bits can now be used to drill hard interlayers and long sections of hard rock formations. PDC bits are increasingly being used, especially as the quality of PDC teeth continues to improve.

Due to improvements in bit design and teeth, the orientability of PDC bits has also increased, further diminishing the advantages of roller cone bits in motor drilling in the past. Currently, PDC bits are crowding out the market for roller cone bits in drilling applications in many formations every day.
