Diamond PDC Drill Bit Characteristics
No need to change the drill bit frequently:
premium-grade polycrystalline diamond compact is used to continuously produce new cutting edges during wear. This self-sharpening feature ensures that the rate of penetration fluctuates by less than 15% in long-distance drilling, eliminating the need for frequent tripping and bit changes.
High-strength matrix wear resistance:
The matrix is sintered from tungsten carbide powder, and the hardness is as high as HRA 88-92. Compared with the ordinary steel drill bit, its erosion resistance is improved by more than 3 times, and it is especially suitable for the complex formation environment with high sand content and strong abrasiveness.
Improve the removal efficiency of cuttings at the bottom of the well:
5-7 replaceable nozzles are configured, and the flow channel design is calculated by CFD. This structure can ensure that the mud can cover the cutting edge by 100, effectively prevent the phenomenon of “mud-packed bit”, and improve the removal efficiency of bottom-hole cuttings.
Impact-resistant interface technology:
non-planar interface bonding technology is used between the composite sheet and the substrate to increase the impact toughness by 40%. Even when encountering interlayer or soft and hard alternating strata, it can effectively reduce the risk of chipping caused by vibration.
Precise lateral stability:
Through a special lateral gauge design, the gauge block is inlaid with natural diamond particles. This not only ensures that the hole diameter deviation after hole forming is controlled within 0.1mm, but also reduces the lateral vibration of the BHA.
Multiple blades share the cutting load:
provide a variety of options from 3 blades to 8 blades. For soft formations, the 3-4 blade design of large flow channels can increase the chip removal space by more than 50%. For extremely hard formations, the multi-blade layout can share the cutting load.

Our factory
Q: How to choose the matrix PDC bit and the steel PDC bit?
A: The matrix bit has strong erosion resistance and is suitable for high abrasive and strong corrosive formations; the steel body bit has larger cutting space and better mechanical strength, and is suitable for fast drilling of high speed, soft to medium hard formations.
Q: Why does the PDC bit collapse?
A: Usually caused by severe axial or lateral vibration, especially when heterogeneous formations are encountered or when operating parameters (such as high speed) are not met. Our impact-resistant interface design effectively reduces such risks.
Q: Is the drill suitable for extremely hard granite?
A: Yes. However, it is necessary to choose a smaller diameter (such as 13mm) cutting teeth and a denser blade layout to increase the cutting density per unit area.
Q: How to judge whether the drill bit has worn out and needs to be replaced?
A: When the rate of penetration (ROP) drops more than 50% under the same parameters, or the torque fluctuates abnormally and cannot be recovered by adjusting the WOB, the trip inspection should be considered.
Q: How does the size of the nozzle affect the drilling efficiency?
A: The nozzle determines the water horsepower (HSI) at the bottom of the well. Smaller nozzles produce a stronger impact force to help clean up the viscous formation; larger nozzles provide a greater flow rate to cool the heat in the hard formation.
Q: Can the PDC bit be repaired and reused?
A: Yes. As long as the carcass or steel body matrix is not seriously damaged, the worn PDC composite sheet can be removed and replaced with a new sheet through a professional heating process, thereby extending the overall life of the drill bit.

Optimization of Precipitation Process by Low Foam Technology
Optimized for HE (high efficiency) and septic systems. The low-foam formula can prevent the foam layer from being too thick to interfere with the solid settlement process in the septic tank, ensure the effective separation of solids, liquids and scum in the wastewater, and improve the treatment efficiency of the system.
Impact-resistant interface technology:
non-planar interface bonding technology is used between the composite sheet and the substrate to increase the impact toughness by 40%. Even when encountering interlayer or soft and hard alternating strata, it can effectively reduce the risk of chipping caused by vibration.
