Roller bit/ Tri cone drilling bit


2022-02-12


The roller cone bit is a key tool for oil drilling, and it is also long used in water well drilling work to drill hard stones together with mud pumps. The quality of its working performance will directly affect the drilling quality, drilling efficiency and drilling cost. Most of the three-cone bit designs are based on practical experience, combined with the method of trial and error, and continuous design and calculation. Therefore, the design accuracy is low, the cycle time is long, and the design quality cannot be improved, and only one bit can be designed for each calculation. low efficiency.

The roller cone bit has the functions of impacting, breaking and shearing the formation rock when it rotates. Therefore, the roller cone bit can be adapted to various soft, medium and hard formations. Especially after the emergence of jet roller cone bits and long nozzle roller cone bits, the drilling speed of roller cone bits was further improved, which is a major reform in the development history of roller cone bits. According to the type of teeth, roller cone bits can be divided into milling teeth (steel teeth) roller cone bits, insert teeth (carbide teeth are embedded on the roller cones) roller cone bits; according to the number of rollers, it can be divided into single cone, double Cone and multi-cone bits. There are many applications at home and abroad, and the most common is the tricone bit.
