Diamond Hole Drilling 9-1/2 inch 7 Blades PDC Bit of Oil Well
1 . Descriptions:
PDC, short for "Polycrystalline Diamond Compact," denotes the use of this advanced diamond material in creating drill bits, a development that has greatly enhanced the efficiency and durability of oil drilling tools.
One example is the S616 PDC bit, a fixed-head bit that rotates as a single unit, ensuring steady and reliable performance during drilling tasks.
Choosing a PDC bit involves considering factors like cutter density, size, bit profile, and blade type, all of which influence how well the bit performs in various drilling conditions and formations.
Our drill bits adhere to the API (American Petroleum Institute) standard, guaranteeing their compatibility and suitability for drilling operations. Available in sizes from 3 to 22 inches with 3 to 9 blades, our PDC drill bits offer a variety of cutter classifications to meet your specific needs and budget constraints.
2. Specification:
For instance, the S716 PDC bit is a fixed-head design that rotates uniformly, ensuring consistent and reliable performance during drilling operations.
When selecting a PDC bit, factors like cutter density, size, bit profile, and blade type play a crucial role in determining its performance across different drilling conditions and formations.

4 . Drill Bit PDC Cutters
At the core of a drill bit are Polycrystalline Diamond Composite (PDC) cutters, which directly engage with the rock, primarily using shearing action for removal. Within the demanding well environment, PDC cutters undergo frequent heating and cooling cycles, posing significant challenges.
PDC cutters with enhanced thermal stability and reduced thermal degradation tend to deliver superior performance, leading to higher Rates of Penetration (ROP) and improved wear resistance. Therefore, optimizing these cutters is crucial for maximizing efficiency.
5. PDC Drill Bit Nozzles
PDC 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
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.
