PDC means Polycrystalline Diamond Composite or Compact. PDC are normally made by sintering many micro-size single diamond crystals at high temperature and high pressure. PDC has good fracture toughness and good thermal stability, and is used in making geological drill bits.
PDC has the advantages of diamond`s high wear resistance with carbide`s good toughness

Proper Application of PDC bit

1. When designing the PDC bit hydraulic parameters, the pump pressure must be greater than 13.0 MPa, using equal or approximate diameter.

2. Due to the poor impact resistance of diamond, the upper and lower drilling rigs cannot touch hard objects, and there must be no falling objects in the well. It is strictly forbidden to drill and dig.

3. It is strictly forbidden to press down when the drill is blocked. Should be connected the Square Drill Pipe to open the pump stroke, but it should not exceed 30 meters Large section ream .

When drilling down to the last two single roots, the joint drill pipe is flushed to the bottom of the well and the circulation is large, and the bottom of the well is circulated clean. Then use a small drill pressure, low speed drilling 0.5 meters, the bottom hole shape.

4. Normal drilling is the preferred drilling parameter. The drilling pressure is 30~60KN and the speed is 217~117 r/min. For every 250~300 meters, a halfway trip must be made.

5. It is not allowed to use PDC bit in the gravel layer and soft and hard staggered formations, and drill when there is falling object at the bottom of the well.

6. It`s good effect in large sections of homogeneous soft to medium hard formations .
