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.

Matrix Body PDC Drill Bit Material  :

The main material components of PDC drill bit body include hard alloy and polycrystalline diamond.

The matrix of PDC drill bit is a composite material composed of hard alloy and Polycrystalline Diamond Compact (PDC).
Hard alloy plays a role in supporting and protecting polycrystalline diamond in PDC drill bits. Hard alloys are usually composed of tungsten carbide (WC) and cobalt (Co), which have high hardness, wear resistance, and compressive strength. These characteristics of hard alloys enable them to withstand high temperature and high pressure environments during drilling, and effectively transmit torque and pressure.


PDC Cutter Manufacture process

The production process of diamond cutting blades mainly includes three methods: sintering diamond cutting blades, welding diamond cutting blades and electroplating diamond cutting blades.

Diamond PDC Cutter Sintering diamond cutting blades:

There are two main methods for sintering diamond cutter , namely cold pressing sintering and hot pressing sintering. Both methods fix the diamond particles on the matrix by pressing and sintering. Cold pressing sintering is carried out at a lower temperature, while hot pressing sintering is carried out at a higher temperature and pressure to ensure that the diamond particles are more firmly fixed in the matrix.
