API Spec Rock Drilling Tools of PDC Diamond Drill Bit
Introduction of Steel-body:
Steel is metallurgically opposite of matrix.
It is capable of withstanding high impact loads, but is relatively
soft and, without protective features, would quickly fail by
abrasion and erosion.
Quality steels are essentially homogeneous with structural limits
that rarely surprise their users.
Steel body bits are manufactured by machining the steel bars per
design.
Advantage of steel-body PDC bits:
The strength and ductility of steel give steel-bit bodies high
resistance to impact loading.
Steel bodies are considerably stronger than matrix bodies.
Because of steel material capabilities, complex bit profiles and
hydraulic designs are possible and relatively easy to construct on
a multi-axis, computer-numerically-controlled milling machine.
A beneficial feature of steel bits is that they can easily be
rebuilt a number of times because worn or damaged cutters can be
replaced rather easily.
This is a particular advantage for operators in low-cost drilling
environments.
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.
