PDC non-planar face cutter PDC ridged cutter 1313 1613 1616
PDC cutters constitute the basic cutting unit of PDC bits, and their performance is crucial to the drilling effect of PDC bits. Overseas bit manufacturers have never stopped the research and development of PDC cutter bits.
The Ridged diamond cutting element has a unique geometry that combines the shearing action of conventional PDC cutters with the compression of tungsten carbide inserts (TCI). The ridged diamond element can be used with matrix and steel-bodied bits to drill unconventional well intervals continuously through the vertical, curve, and lateral
The crushing function in one, the advantages are as follows:
(1) Increased cutting efficiency for instant ROP improvement
The crushing and shearing action of the Axe element achieves at least 22% deeper penetration to provide higher instantaneous ROP using the same weight on bit and rpm applied to conventional PDC cutters. The key is in the ridge-shaped geometry which yields a diamond table that is 70% thicker than a conventional cutter, while providing higher frontal impact resistance. This feature translates into improved durability and dull conditions for maintaining maximum ROP throughout the run.
(2) Enhanced control in directional applications
The reduced cutting force required by drill bits translates to less overall torque, reduced reactive torque fluctuation, and better toolface control in curve applications. This advantage enables better build rates and higher overall ROPs, helping maximize production zone exposure and minimize drilling time.
How PDC Cutters are made
PDC Cutters are made from tungsten carbide substrate and synthetic diamond grit. It is made using a combination of high temperature and high pressure with catalyst of cobalt alloy to help bond diamond and carbide during the sintering process. During the cooling process, the tungsten carbide shrinks at a rate of 2.5 times faster than the diamond, which combines Diamond and Tungsten Carbide together and thereafter forms a PDC Cutter.
Characteristics and Applications
Since PDC Cutters consist of diamond grit and tungsten carbide substrate, it combines advantages of both diamond and tungsten carbide and featured high abrasion resistant, high impact resistant and high thermal stable.
Now PDC Cutters are widely applied to oilfield drilling, gas and geological exploration, coal mining and many other drilling and milling applications, tooling as PDC Drill Bits, such as Steel PDC Drill Bits & Matrix PDC Drill Bits for oil drilling and
Tri-cone PDC Drill Bits for coal mining.
PDC cutters are produced with high-quality man-made diamond powder and tungsten carbide powder. The PDC cutters combine the high hardness and abrasion resistance of diamond and tungsten carbide, which are widely used for different drilling tools:
1. mining bits
2. geological bits
3. diamond DTH bit
4. diamond pick and other drilling tools.
Including below filed:
1. geothermal energy drilling
2. mining
3. water well
4. natural gas drilling and oil well drilling.
