Diamond Composite Drill Bits

The drill bit is an integrated drill bit. The entire drill bit has no moving parts and a relatively simple structure. It has high strength, high wear resistance and impact resistance. It is one of the three new drilling technologies in the world in the 1980s. Field use has proved that the diamond composite drill bit has the advantages of fast speed, high footage, long life, stable operation, few downhole accidents and good wellbore quality when drilling in soft-medium-hard formations. And compared with diamond drill bits, it has the advantages of low cost and wide application range.

Advantages of diamond composite drill bits

1. The force balance design makes the drill bit have good guidance, suitable for downhole motors for directional drilling, and has small radial vibration;

2. The reasonable arrangement of patented PDC composite pieces of different structures at different positions of the drill bit makes the drill bit have strong aggressiveness and abrasion resistance;

3. The strong aggressive design enables the drill bit to obtain high mechanical drilling speed;

4. The dynamic flow field simulation technology is applied to hydraulic design to optimize the bottom flow field, which is conducive to improving the chip removal speed and preventing mud packing.

5. Because the materials of PDC drill bits are mainly cast tungsten carbide and diamond composite sheets, they have a long life and high value. 5. Because the materials of PDC drill bits are mainly cast tungsten carbide and diamond composite sheets, they have a long life and high value.
