Hard Rock Drilling 9-1/2 Inch 6 Blade PDC Bit Of Oil Well

Hard Rock Drilling 9-1/2 Inch 6 Blade PDC Bit Of Oil Well​

1 . Descriptions:

PDC, short for "Polycrystalline Diamond Compact," signifies the use of advanced diamond material in drill bit production, significantly enhancing efficiency and durability in oil drilling.

An example is the S616 PDC bit, a fixed-head tool that rotates as a single unit, ensuring consistent and reliable performance during drilling.

Selecting a PDC bit involves factors like cutter density, size, bit profile, and blade type, influencing its effectiveness in various drilling conditions.

Our PDC drill bits meet API standards, ensuring compatibility for drilling operations. Available in sizes from 3 to 22 inches with 3 to 9 blades, they offer various cutter classifications to match specific needs and budgets.

2. Specification:

PDC bits like the S616 or M616 are specified with a 6-blade steel or matrix body and a 16mm main cutter. The IADC code indicates if the bit suits hard, soft, or specific profile formations, offering additional insights.

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.
