The Characteristics of PDC Steel Body Bits
PDC steel body drill bit (polycrystalline diamond composite drill bit) has become one of the core tools for modern efficient drilling due to its unique design and advanced materials. It uses high-strength alloy steel as the substrate and is embedded with high-density polycrystalline diamond composite (PDC) as the cutting unit, which combines sharpness, wear resistance, and impact resistance, and is suitable for the efficient rock breaking needs of extremely soft to extremely hard formations.
By scientifically arranging teeth, optimizing blade profiles, and designing hydraulic structures, rapid cutting and crushing of rock layers can be achieved, significantly improving mechanical drilling speed and single pass feed life. The steel structure has strong stability and excellent fatigue resistance, which can effectively suppress downhole vibration and displacement, ensuring precise and controllable drilling trajectory.
At the same time, the integration of high-quality PDC cutters and precision manufacturing processes enables them to maintain stable performance in high-temperature and high abrasive formations, significantly reducing the cost of frequent drilling and replacement, and achieving comprehensive economic benefits far beyond traditional roller drill bits.
With the ultimate pursuit of technical details, Hebei Ruishi's PDC steel body drill bits have been used in multiple deep oil and gas field projects at home and abroad, winning wide recognition from industry customers with lower comprehensive costs and higher drilling profits.
Structure and Materials: PDC steel body drill bits adopt a steel body structure, mainly made of alloy steel, with high strength and toughness. The cutting teeth are usually polycrystalline diamond (PDC) composite cutters, which have high hardness and good wear resistance, and can effectively improve the service life and drilling efficiency of the drill bit.
Blade and cutting tooth configuration: This drill bit (usually) is equipped with three to nine blades, each with a main cutting tooth distributed on it.
Applicability: PDC steel body drill bits are suitable for various soft and hard formations, and their design can effectively deal with formations containing abrasive interlayers, while also having good impact resistance and wear resistance.
Drilling efficiency: PDC steel body drill bits are known for their high cutting efficiency and can complete drilling tasks in a short period of time.
Chip removal capability: The drill bit design includes optimized bottom hole flow field and chip removal groove, which can reduce repeated cutting, improve drilling speed, and extend drill bit life.
Multifunctionality: PDC steel body drill bits are suitable for various well types such as vertical wells, directional wells, and horizontal wells, and can meet the needs of different working conditions.
Technological improvement: With the development of technology, the design of PDC steel body drill bits is constantly optimized, such as adjusting the crown shape, tooth density, and increasing the chip groove area, further improving their performance in complex formations.
