Abstract
Methods, systems and compositions for manufacturing downhole tools and downhole tool parts for drilling subterranean material are disclosed. A model having an external peripheral shape of a downhole tool or tool part is fabricated. Mold material is applied to the external periphery of the model. The mold material is permitted to harden to form a mold about the model. The model is eliminated and a composite matrix material is cast within the mold to form a finished downhole tool or tool part.
Claims8
A downhole tool part for drilling subterranean material, the downhole tool part comprising:
- a composite matrix composition comprising a constituent material and a carbide material, the composite matrix composition further comprising:
- a continuous phase of the constituent material;
- and
- a eutectic particulate phase formed from a eutectic composition of the constituent material and the carbide material;
- and
- a particulate material dispersed throughout the composite matrix composition of the downhole tool part, the particulate material comprising at least one material selected from the group consisting of polycrystalline diamond compact (PDC), thermally stable polycrystalline diamond (TSP), cubic boron nitride (CBN), and polycrystalline cubic boron nitride (PCBN).
