Product Description

Hard Rock Drilling 4-1/2 inch 5 Blades PDC Drill Bit Of oilfield Tool
 

Product Description

.
PDC (Polycrystalline Diamond Compact) bits play a crucial role in oil drilling due to their durability and efficiency. Utilizing synthetic diamond cutters, they outlast conventional bits, leading to cost savings.

These bits are adept at drilling through challenging rock formations, delivering faster drilling speeds with enhanced rates of penetration (ROP). Their precision in directional drilling enables accurate navigation through intricate well paths.

By enhancing wellbore quality, PDC bits boost productivity and longevity. They guarantee stability, control, and safety during drilling, thereby reducing downtime and ensuring operational efficiency.
 

The performance of the drill is influenced by several factors:

+Body material:  
+Density of the cutting elements:  
+Cutter size or type:  
+Bit profile: 

 
How to choose the correct drill bit ,it is very import for drilling enigineer.

Our Advantages

 During the drill bit design process, there are much more optional feature for you choose to Improve the drill bit cutter performance .
as below , but not limited on this .  

PDC Drill Bit 'S Cutters
The primary contact point of a drill bit is its PDC cutters, which are made of Polycrystalline Diamond Composite (PDC). PDC bits excel at efficiently removing rock by chopping through it.

Operating in a challenging environment, PDC cutters experience frequent heating and cooling within the well. To maximize performance, PDC cutters with superior thermal stability and minimal thermal deterioration are preferred. These optimized cutters demonstrate higher Rate of Penetration (ROP) and enhanced wear resistance.
.
PDC Drill Bit'S  Nozzles
Drill bit nozzles play a crucial role in maintaining the temperature of the PDC cutters and clearing the cutting zone. By keeping the PDC cutters cool, the nozzles contribute to their longevity and performance.

The positioning and angle of these nozzles significantly influence the effectiveness of the drill bit. Properly placed nozzles ensure efficient cooling and help prevent heat-related issues. Additionally, the strategic arrangement of fluid channels, in conjunction with the nozzle location, facilitates improved removal of cuttings during drilling operations.



Steel Body PDC Bits
The antithesis of a matrix body is a steel body. Although it is softer and lacking protective features, it is capable of withstanding severe impact loads. Steel bit bodies provide a high level of impact resistance due to the strength and ductility of steel.
Matrix bodies are significantly weaker than steel bodies.
Steel bits have the advantage of being easily rebuilt multiple times due to the ease with which worn or damaged cutters can be swapped out. Operators who operate in low-cost drilling environments will particularly benefit from this.
In contrast to roller cones, polycrystalline diamond compact (PDC) drill bits have a single, non-moving body. In consolidated formations, the bit can operate at faster rotation rates because the fixed-cutters efficiently shred the rock.

Drill Bit PDC Cutters
It's crucial to first recognize the significance of Polycrystalline Diamond Compact (PDC) Cutters.
PDC Cutters improve the functionality of PDC drill bits by increasing their dynamic stability in a variety of difficult vertical and directional drilling applications.

One-of-a-kind polycrystalline diamond cutter has exceptional strength, hardness, and toughness.

It is therefore perfect for a variety of material removal (cutting) procedures.

PDCs are produced utilizing tungsten carbide, diamond, high pressure, and heat.


 PDC Bit Manufactuer proces :

The PDC is manufacture by crow and connection and . The crow is steel and matrix  . Different crow have different process , finally ,it is the connection welding and PDC Welding .
