In fields such as geological exploration and resource development involving hard rock drilling, traditional drill bits tend to wear out easily in hard rock, leading to low drilling efficiency and increased costs. The emergence of polycrystalline diamond bits, with their excellent wear resistance and cutting efficiency, has brought revolutionary breakthroughs to hard rock drilling. GREAT has pioneered this innovative technology through technological advancements. This article will focus on the application of polycrystalline diamond bits in hard rock drilling.
Polycrystalline diamond bits, also known as PDC bits, are revolutionary tools that use polycrystalline diamond compact cutters as their cutting surface. There are two types of PDC bits: matrix-body and steel-body bits. Matrix-body bits are made by sintering matrix powder in a sintering furnace and are more wear-resistant than steel-body bits, making them suitable for deep oil and gas extraction. Steel-body bits are made from AISI 4145H steel and heat-treated, making them easier to maintain. Currently, these products are widely used in oil and gas extraction, geothermal well drilling, reverse circulation drilling, and horizontal directional drilling.
Diamond is one of the hardest known materials, offering unparalleled wear resistance and abrasion resistance. This exceptional hardness results in longer tool life, reducing the frequency of bit replacements and lowering operational costs.
The sharp and wear-resistant cutting edges of polycrystalline diamond bits accelerate penetration rates in hard rock formations. Additionally, PDC bit designs can provide greater contact area and more uniform cutting force, thereby enhancing drilling speed.
The high thermal conductivity of diamond helps dissipate heat during drilling, reducing the risk of bit failure due to overheating.
The high wear resistance and cutting efficiency of PDC bits significantly enhance the operating speed in hard rock drilling, shortening drilling cycles.
The long lifespan of PDC bits reduces the frequency of replacements, thereby lowering maintenance costs.
The stability and reliability of PDC bits reduce the risk of unexpected downtime and accidents during drilling operations.
