Common specifications: Core drills that are compatible with coring tools such as Chuan 8 - 4, Chuan 8 - 3, and Chuan 5 - 4.

The PDC oil core drills are custom - designed for different working conditions and formation conditions. This type of drill bit needs to be used in conjunction with special coring tools. Professional software is used for force - balance design and calculation of this kind of drill bit, which improves the drill bit's stability and prevents its early failure. Flow - field simulation calculation is carried out to optimize the hydraulic design of the drill bit, enhancing its cleaning and cooling capabilities. The arc - shaped crown design and blade - type tooth arrangement improve the mechanical drilling speed, resulting in a high coring rate and a long service life. The use of diamond composite blades for gauge protection extends the service life of the drill bit.
