Diamond 4-1/2" PDC Drill Bit of Oil Drilling Tool

1. Descriptions of PDC Drill Bit 

PDC bit is a fixed cutter drilling tool with polycrystalline diamond compact cutters used for rock drilling in oil, mining, water or gas wells. This drilling tool is manufactured according to API specifications and is API certified. The PDC cutters are made of synthetic diamond material, which is the hardest known material, making it extremely wear-resistant. Compared to tricone bits, PDC bits generally offer higher drilling efficiency but at a higher cost.

PDC bits utilize multiple diamond cutters arranged in specific patterns to shear the rock formation. These bits are mainly categorized into two types: matrix body PDC bits and steel body PDC bits, designed for different drilling conditions. Matrix body PDC bits are typically used in more abrasive formations, while steel body PDC bits are often employed in softer formations.

2. Specification:

PDC bits such as the S616 or M616 are specified with a 6-blade steel or matrix body and a 16mm main cutter. The IADC code indicates whether the bit is suitable for hard, soft or specific profile formations, providing additional insight.
So the IADC 323 have different mean of the PDC drill bit.

4 . Drill Bit PDC Cutters

At the heart of a drill bit are polycrystalline diamond composite (PDC) cutters, which engage directly with the rock, using primarily shearing action for removal. In the demanding environment of a well, PDC cutters undergo frequent heating and cooling cycles, which pose significant challenges.
PDC cutters with improved thermal stability and reduced thermal degradation tend to perform better, resulting in higher rates of penetration (ROP) and improved wear resistance. Optimising these cutters is therefore critical to maximising effiency.

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.PDC Drill Bit Optional Feature :

There are much more feature of the PDC drill bit for choose ,which is increase the PDC bit stablility ,wear resistance and rear ,cutter performance and

7. 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.
