Product Description
Well Diamond Drilling 5-7/8 Inch PDC Bit of Oilfield
1 . Descriptions:
PDC drill bits are known for their exceptional drilling efficiency and extended lifespan. These characteristics enable them to penetrate formations rapidly, resulting in reduced drilling time and costs. Additionally, their durability minimizes the frequency of replacement and maintenance requirements.
Suitable for various drilling methods such as rotary and vibration drilling, PDC drill bits offer versatility and ease of operation. They allow for flexibility in adjusting drilling parameters to achieve desired drilling outcomes.
One notable advantage of PDC drill bits is their ability to generate lower levels of noise compared to other types of drill bits. This feature not only improves the working environment for operators but also minimizes disturbances to the surrounding environment. By prioritizing safety and environmental friendliness, PDC drill bits contribute to sustainable drilling operations.

4 . PDC Drill Bit Cutters
Polycrystalline Diamond Composite (PDC) cutters are the main point of contact for a drill bit. PDC drill bits remove the rock mainly by shearing.
The PDC cutters are exposed to a lot of heating and cooling down the well, a very challenging environment.
PDC cutters that have lower thermal degradation and more thermal stability generally achieve higher ROP and increased wear resistance. So, optimizing the cutter is important.
Accorrding to the Api ,the cutter size are as below :
1 indicates PDC cutters > 24 mm in diameter.
2 represents cutters from 14 to 24 mm in diameter.
3 indicates PDC cutters < 14 but > 8 mm. 4 is used for cutters < 8 mm.
5. PDC Drill Bit Nozzles
Drill bit nozzles help clear the cutting area and cool the Polycrystalline Diamond Composite (PDC) cutters.
Effective placement of these nozzles along with the angle they are set at plays a critical role on how efficient the drill bit performs.
Fluid channels also complement nozzle placement to improve the clearing of cuttings.
6. Steel Body PDC Bits manufacture process
Steel body of PDC Bit is the opposite of matrix body. It can of withstanding high impact loads, but is softer and lacks protective features. The strength and ductility of steel give steel-bit bodies high impact resistance. Steel bodies are considerably stronger than matrix bodies.
A beneficial feature of steel bits is that they can easily be rebuilt a number of times because worn or damaged cutters can be replaced rather easily. This is a particular advantage for operators in low-cost drilling environments.
Polycrystalline diamond compact (PDC) drill bits are different than roller cones in that they are one piece bodies with no moving parts. The fixed-cutters shred the rock, so the bit is able to operate with higher rotation speeds more efficiently in consolidated formations.
