API Spec oilfield 13-1/4 " Oilfield Diamond PDC Bit

1 . Descriptions:

PDC stands for "Polycrystalline Diamond Compact," representing an advanced diamond material used in the manufacturing of drill bits, significantly improving efficiency and durability in oil drilling operations.

For instance, the S616 PDC bit is a fixed-head tool that rotates as a single, cohesive unit, ensuring consistent and dependable performance while drilling.

Choosing a PDC bit involves considering factors such as cutter density, size, bit profile, and blade type, all of which impact its performance in different drilling conditions.

Our PDC drill bits adhere to API standards, ensuring they are compatible with drilling operations. Available in sizes ranging from 3 to 22 inches with 3 to 9 blades, these bits offer various cutter classifications to suit specific requirements and budgets.

2. Specification:

PDC drill bits such as the S616 or M616 feature a construction with a 6-blade steel or matrix body and a 16mm primary cutter. The IADC code provides valuable information on whether the bit is suitable for hard, soft, or specific profile formations, providing further clarity.

Therefore, the IADC 323 designation signifies distinct characteristics of the PDC Drill Bit.

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.
