Application, Use, and Development Trends of PDC Bits

Successful Application of PDC Bits

Since the successful application of PDC bits in oil and gas drilling, the industry has undergone "earth-shaking" changes. This is especially true with the advent of innovations such as polycrystalline diamond composite layers that significantly improve wear resistance and impact resistance, non-planar interface technology that enhances the bonding strength between the diamond layer and the hard substrate, anti-whirl technology to reduce torsional impact, cobalt filtering processes to enhance the thermal stability of the composite, hydrodynamic optimization based on computational fluid dynamics, computer-aided modeling, big data-based drill bit selection and personalized design, and intelligent manufacturing technologies.

Precautions for Using PDC Bits

PDC bits are suitable for soft to medium-hard homogeneous formations and are not suitable for drilling alternating soft and hard formations and gravel layers.

Compared to roller cone bits, PDC bits should be used with low weight on bit (WOB) and high rotational speed for drilling.

Before descending a PDC bit into the well, the bottom of the well should be clean and free of metal debris. When drilling with a new bit, first use a small WOB and low rotational speed to grind the bottom of the well and shape it.

PDC bits are integral drill bits with no moving parts, making them suitable for high-speed turbine drilling.

Development Trend of PDC Bits

In recent years, the development of PDC bits has been extremely rapid. Their drilling performance and variety have basically met the needs of oil and gas drilling, accounting for nearly 80% of the global oil and gas market share, with the proportion of total drilling footage exceeding 90%. However, there is still room for further improvement. 

To meet the needs of modern oil and gas extended reach wells, long horizontal section horizontal wells, and ultra-deep wells, petroleum companies and research institutions are actively exploring aspects such as the materials, shapes, and machining processes of PDC cutting teeth, their configuration on drill bits, drill bit structure, hydrodynamics, cutting principles, and manufacturing processes.
