Diamond Rock PDC Drill Bit 8 1/2 " Oil Well Drilling Bit of Drilling Rig Bit
Description :
The PDC (Polycrystalline Diamond Compact) drill bit is a highly advanced tool utilized for cutting through underground rock formations. Its usage is tailored to specific types of formations, as different rock compositions require different drill bit designs. When dealing with exceptionally hard rock, a specialized drill bit is employed, which is meticulously crafted by skilled professionals after carefully evaluating the formation characteristics :
It's important to note that the manufacturing process may vary slightly among different PDC drill bit manufacturers. Each manufacturer may have their proprietary techniques, materials, and quality control procedures. The process described above provides a general overview of the typical steps involved in PDC drill bit manufacturing.
Description PDC Drill Bit :
PDC drill bits with high hardness and a fixed blade design offer outstanding cutting efficiency and wear resistance. They are suitable for various formations, enhancing drilling speed and operational efficiency.
The blades of PDC drill bits are made of polycrystalline diamond composite material, providing excellent anti-plugging performance and high-temperature adaptability. They can operate reliably in harsh downhole environments.
With a variety of blade shapes available (such as circular, wedge, or conical), PDC drill bits can be selected based on specific requirements to adapt to different geological conditions, delivering excellent drilling stability and high-quality boreholes.
Application:
There are two type of PDC Drill bit of oilfield : Steel body and Matrix body . Both of them are used for the Diamond PDC Drill Bit But different material and design and usage formation :
Matrix body PDC bits are primarily used for these application :
---Soft to medium-hard formations
---High volume
---High sand
---Applications where the same bit will need to be used for several bit runs
Steel body PDC bits are primarily used for these applications:
---Drilling in shale formations
---Soft limestone sites
---Fast drilling in the stratum
---Natural gas drilling
---Deep wells
---Abrasive formation

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.
