12-1/2 Inch API PDC Drill Bit for Diamond Drilling Rock Tool
PDC drill bits:
Polycrystalline diamond materials, for use in polycrystalline
diamond compact (PDC) bits, are one of the most important material
advances for oil drilling tools in recent years.
Fixed-head bits rotate as one piece and contain no separately
moving parts.
When fixed-head bits use PDC cutters, they are commonly called PDC
bits.
Since their first production in 1976, the popularity of bits using
PDC cutters has grown steadily, and they are nearly as common as
roller-cone bits in many drilling applications.
Development of PDC bits:
Fortunately, both steels and matrix are rapidly evolving, and their
limitations are diminishing.
As hard-facing materials improve, steel bits are becoming extremely
well protected with materials that are highly resistant to abrasion
and erosion.
At the same time, the structural and wear-resisting properties of
matrix materials are also rapidly improving, and the range of
economic applications suitable for both types is growing.
Today's matrix has little resemblance to that of even a few years
ago. Tensile strengths and impact resistance have increased by at
least 33%, and cutter braze strength has increased by ≈80%.
At the same time, geometries and the technology of supporting
structures have improved, resulting in strong, productive matrix
products.
Applications:
Water Well drilling
Having higher ROP, diamond PDC drill bits are also widely used as
water well drill bits for geothermal drilling.
Oil & Gas drilling
- It is the most widely used bit in the Oil &Gas drilling.
Hydraulic factors are very important during drilling.
- PDC bits have been used in the areas that can't be available
previously, such as harder, more abrasive, and more variable
formations.
- The diamond PDC bit is mainly composed of the bit body, cutting
teeth, nozzle, gauge protection, and API Thread connection.
