Product Description

Oilfield Diamond Drill Bit 9-1/2inch PDC Cutter Drilling Of API Spec
 

Product Description

PDC bits are specially designed for fast drilling in shale, limestone, and sandstone formations. They come in two types of bodies: steel body and matrix body. Both types offer the same cutting effectiveness. strickly speak, the matrix body material is more hard than steel body but the strength is not so well comparably with steel body .  Each of the body have their own advantage : 

The performance of the drill bit is influenced by several factors:

Body material: This refers to the material used to construct the bit's body.
Cutter density: It refers to how the cutting elements are arranged and their quantity on the bit.
Cutter size or type: This describes the size or type of the cutting elements on the bit.
Bit profile: It determines the shape and design of the bit's cutting structure.

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.


Why choose PDC Drill Bit
PDC bits have the fixed blades with large, hard, abrasion-resistant cutters manufactured from a boned mass of microcrystalline synthetic diamonds and designed to excavate hole by shearing the formation while tricone insert bit works by crushing it.

Softer the formation and homogenous smaller the number of blades and bigger the size of the PDC cutters.

They drill very fast in soft to moderately hard formations as Sand, Shale, Clay and Siltstone.
