Product Description

Product Description

Production Name :

PDC bit is a fixed cutter drilling tool with polycrystalline diamond compact cutters used for rock drilling in oil, mining, water or gas wells. This drilling tool is manufactured according to API specifications and is API certified. The PDC cutters are made of synthetic diamond material, which is the hardest known material, making it extremely wear-resistant. Compared to tricone bits, PDC bits generally offer higher drilling efficiency but at a higher cost.

PDC bits utilize multiple diamond cutters arranged in specific patterns to shear the rock formation. These bits are mainly categorized into two types: matrix body PDC bits and steel body PDC bits, designed for different drilling conditions. Matrix body PDC bits are typically used in more abrasive formations, while steel body PDC bits are often employed in softer formations.

The selection of PDC bits is customized based on formation characteristics. PDC bits perform exceptionally well in soft to medium-hard, non-abrasive formations. For hard and abrasive formations, specially designed PDC bits with enhanced cutter technology are available .This advanced drilling tool is widely applied in various fields including oil/gas well drilling, mining operations (such as coal and metal mines), water well drilling, and geological exploration projects, offering superior drilling performance and efficiency in suitable formations.



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 :

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
