Manufacturers supply high-quality pdc diamond drill bits, sintered body drill bits, matrix diamond composite drill bits

Carcass PDC bit The matrix-type diamond composite (PDC) drill is a cutting-type drill in which the diamond composite 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 an artificial polycrystalline diamond composite sheet, and gauged with natural diamond. Steel body type PDC drill bit Steel body PDC drill bits are machined and formed with nickel, chromium, and molybdenum alloys. After heat treatment, a hole is drilled on the drill bit body, the synthetic polycrystalline diamond composite sheet is pressed (closely fitted) into the drill bit body, and cylindrical tungsten carbide is used to gauge the diameter. Applicable industry classification Composite bit for geological prospecting The composite piece drill bit is mainly used for geological survey and exploration, which is suitable for soft to medium-hard rock formations. At present, the new type of composite piece newly developed by some manufacturers can be applied to rock formations with tenth-level hardness.

Coal field drilling adopts composite drill bit It is mainly used for drilling and mining upper coal seams in coal mines. Generally speaking, the rock formations in coal fields are relatively soft, and composite drill bits are widely used, such as bolt drill bits and three-wing drill bits. Composite drill bit for petroleum exploration The drill bit is mainly used in the drilling of oil and gas fields. At present, the composite chip drill bit for oil field is the cost and requirement of all composite chip drill bits. It can be said to be the nobleman in the composite drill bit. Development statusedit In recent years, the quality and type of PDC cutting teeth have undergone tremendous changes. If you compare the teeth of the 1980s with the teeth of today, the difference is quite large. Due to the changes in the mixing process and the manufacturing process, the quality performance of today's cutting teeth is much better, which greatly improves the erosion and impact resistance of the drill bit.

The engineers also optimized the interface between the tungsten carbide substrate and the 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 arrangement. Now, PDC products can be used in areas where they could not be used before, such as harder, more abrasive and changeable formations. This expansion into new areas has had a great impact on the balance between diamond (fixed cutter) bits and roller cone bits. At first, PDC drill bits could only be used in soft shale formations because hard interlayers would damage the drill 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 drill bits are becoming more and more people's choice, especially with the continuous improvement of the quality of PDC teeth, this situation has become more and more prominent. Due to the improvement of bit design and teeth, the orientability of PDC bit is also improved.
