The most used in oil drilling and geological drilling is the cone bit. The cone bit has the effect of impacting, crushing and shearing the formation rock when rotating, so the cone bit can adapt to various soft, medium and hard formations. Especially after the emergence of jet cone bit and long nozzle cone bit, the drilling speed of cone bit is greatly improved, which is a major revolution in the development history of cone bit.
PDC BitBitOilfield BitCone bit according to tooth type can be divided into milling tooth (steel tooth) cone bit, insert tooth (insert carbide teeth on the cone) cone bit; According to the number of rollers, it can be divided into single, double, three-cone and multi-cone bits. At present, tricone bit is the most commonly used at home and abroad.
