Product Description
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.
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
There are two type of manufacture of them :
