PDC cutter for oil drilling bits

PDC cutter is mainly applicable for PDC drilling bit for drilling into soft and intermediate-hardness stratum.
Alias: 
Polycrystalline Diamond Compact
PDC Inserts
Application:
Petroleum
Oil field PDC bits
Size:
0608, 0808, 1304, 1308, 1313, 1613, 1616, 1913, 1916

The diamond drill bit is used in nearly all applications including geothermal energy drilling, mining, water well and natural gas drilling, and oil well drilling.
Total depths range from 100' to 20,000'.

Specification

PDC cutters (Polycrystalline Diamond Composite) are consist of polycrystalline diamond layer sintered with tungsten carbide substrate under ultra-high temperature and pressure.

 

Application of PDC cutter

PDC cutters are widely used for petroleum and oil field PDC bit, geological PDC exploration bits, gas exploration bits, PDC coal mining drill bits.

PDC is mainly applicable for PDC drilling bit for drilling into soft and intermediate-hardness stratum.

 

Advantages of PDC cutters

◆ New cutting surfaces will appear during the course of abrasion, which keeps effective cutting rocks

◆ High strength, high hardness and high wearing property of diamond layer as well as good self-sharpening

◆ PDC drilling bit made of such PDC will break up rocks depending on shearing action when it works, which is more effective than crushing of rocks by roller cone bit or plowing and grinding of rocks by diamond impregnated bit

◆ The serrate structure combination between polycrystalline diamond layer and hard alloy substrate allows more fixed combination between the two layers and more impact resistance of the whole PDC.

Correct use of PDC drill bits
●PDC bits work best in large sections of homogeneous soft to medium hard formations.
Not suitable for drilling gravel layer and soft and hard interlaced formation.
●It adopts low drilling pressure, high speed, and large displacement for drilling, and the drill bit has a good effect.
●Before the drill bit goes into the well, the bottom of the well should be cleaned to ensure that there are no metal falling objects.
●When the drill bit just goes into the well, it is necessary to use a small WOB and low rotational speed to run in harmony, and resume normal drilling after the bottom hole is formed.
●PDC drill bits are integral drill bits without any moving parts and are suitable for high-speed turbine drilling.
 
How to choose the size of PDC cutter
As a general rule, large cutters (19mm to 25mm) are more aggressive than small cutters. However, they may increase torque fluctuations.
 
Smaller cutters (8mm, 10mm, 13mm, and 16mm) have been shown to drill at a higher rate of penetration (ROP) than large cutters in certain applications. One such application is limestone for example. Bits are designed with smaller cutters but more of They can withstand higher impact loading.
 
Additionally, small cutters produce smaller cuttings while large cutters produce larger cuttings. Large cuttings may cause problems with the hole cleaning if the drilling fluid cannot carry the cuttings up.
