Oil Well 6-1/2 Inch Diamond Fixed PDC Drill Bit Of Drilling Tool

Oil Well 6-1/2 Inch Diamond Fixed  PDC Drill Bit  Of  Drilling Tool 

1 . Descriptions:

PDC Drill Bit is highest performance drilling tool of the down hole drilling tool . The PDC Drill bit should be used the homogenous Rock formation which can get the best performance .

There drill bit have verial modle ,but when your choose the PDC Drill ,you should be pay attention to the Key factors for PDC drill bit selection: 

1. Cutting tooth density & size: Match formation hardness. High density for durability, low for speed; large teeth for soft strata, small for hard.

2. Bit profile: Flat for vertical drilling, conical for directional, stepped for interbedded formations.

3. Blade type: Straight for hard strata, spiral for soft-medium, mixed for complex conditions. 

2. Specification:

PDC bits such as the S516 or M516 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 S323 have different mean of the PDC drill bit for soft or hard formation ,cutter size and profile .

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. 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.
 
Material Capacity & Following Standard
 

 
 
The steel materials of PDC Drill Bit is AISI 4145H alloy structural steel .
 
‌AISI 4145H alloy structural steel‌: This is a steel specifically used for oil drilling tools, especially for the manufacture of heavy-duty drill pipes. AISI 4145H steel has good wear resistance and toughness, can withstand high pressure and high temperature environments, and is suitable for deep and ultra-deep well drilling operations‌45.
