Why is the PDC drill bit so good?
PDC drill bit is very specific to the formation. In directional construction, as the strength of the formation increases, the tool face changes greatly. The PDC drill bit mechanical drilling speed is significantly higher than that of the roller cone bit, and it can be achieved with a smaller WOB. The drilling speed of the roller cone bit under the large drilling pressure, and the pump pressure lower than that of the roller cone bit, can achieve a higher drilling speed at a higher speed, the load

Why is the PDC drill bit so good?
PDC drill bit is very specific to the formation. In directional construction, as the strength of the formation increases, the tool face changes greatly. The PDC drill bit mechanical drilling speed is significantly higher than that of the roller cone bit, and it can be achieved with a smaller WOB. The drilling speed of the roller cone bit under the large drilling pressure, and the pump pressure lower than that of the roller cone bit, can achieve a higher drilling speed at a higher speed, the load of the machine pump equipment is small, and the cost of the drill bit is also significantly reduced. And today let's talk about the PDC drill bit.Structural characteristics of PDC drill bit.PDC drill bit is composed of drill body, PDC drill bit cutting teeth, and nozzles. According to the difference of structure and manufacturing process, the PDC drill bit is divided into two series: steel body and carcass. The entire drill body of the rigid PDC drill bit is made of medium carbon steel and processed by mechanical manufacturing technology. Drill holes on the working surface of the drill bit, and fasten the PDC drill bit cutting teeth on the crown of the drill bit in a press-fitting manner. The crown of the drill bit is treated with a surface hardening process (spraying tungsten carbide wear-resistant layer, carburizing, etc.) to enhance its erosion resistance. The main advantage of this kind of drill bit is the simple manufacturing process.
