9-1/2 Inch S516 PDC Diamond Drill Bit of Oilfield Natural Gas Drilling
Product Parameters
PDC drill bits
Polycrystalline diamond materials, for use in polycrystalline diamond compact (PDC) bits, are one of the most important material advances for oil drilling tools in recent years.
Fixed-head bits rotate as one piece and contain no separately moving parts.
When fixed-head bits use PDC cutters, they are commonly called PDC bits.
Since their first production in 1976, the popularity of bits using PDC cutters has grown steadily, and they are nearly as common as roller-cone bits in many drilling applications.
Steel-body
Steel is metallurgically opposite of matrix. It is capable of withstanding high impact loads, but is relatively soft and, without protective features, would quickly fail by abrasion and erosion.
Quality steels are essentially homogeneous with structural limits that rarely surprise their users.
Steel body bits are manufactured by machining the steel bars per design.
Advantage of steel-body PDC bits
The strength and ductility of steel give steel-bit bodies high resistance to impact loading.
Steel bodies are considerably stronger than matrix bodies.
Because of steel material capabilities, complex bit profiles and hydraulic designs are possible and relatively easy to construct on a multi-axis, computer-numerically-controlled milling machine.
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.

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.
.
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.
