The manufacturer of PDC for oil drilling bit tells you that the PDC drill bit is made of polycrystalline diamond into cutting blocks, and then a certain number of cutting blocks are mounted (or sintered) on the bit body.

The cutting block is made of a thin layer of synthetic polycrystalline diamond (about 0.6-2.5mm) and a bottom layer of tungsten carbide sintered into a whole. The PDC for oil drilling bit manufacturer tells you to weld the composite sheet and the cylindrical body together to form a cutting element.
The structure of PDC bit is divided into two series: steel body and carcass according to different materials and manufacturing processes.
Parabolic type: It has a larger surface of the drill bit and can be mounted with more cutting blocks to improve the wear resistance and footage of the drill bit. The manufacturer of PDC for oil drilling bit tells you that its shape can concentrate the lateral thrust towards the center, reduce the deviation of the borehole direction, and help overcome the well deviation.
Double cone type: There are inner cone and outer cone, which can keep the drill bit stable. The outer cone surface is longer and can be inlaid with more cutting blocks. When drilling hard interlayers or hard formations, the top cutting block is easily damaged by impact.
Short cone: PDC for oil drilling bit manufacturers tell you that it is beneficial to drill through hard interlayers. The surface area of the drill bit is small, so the hydraulic power is more concentrated and the cleaning is better.
The manufacturer of PDC for oil drilling bit tells you the rock breaking mechanism of the PDC bit. The cutting block of the PDC bit is used to break the rock by scraping and squeezing. Under the action of, move forward to shear the rock. Make full use of the low shear strength of rocks. The manufacturer of PDC for oil drilling bit tells you that there is no "holding effect" caused by the pressure difference when the PDC bit breaks the rock when the PDC bit breaks the rock.
