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.
Advantage of matrix-body PDC bits
Matrix-body PDC bits are commonly preferred over steel-body bits for environments in which body erosion is likely to cause a bit to fail. For diamond-impregnated bits, only matrix-body construction can be used.
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.
