The design of tricone bits（rotary cone bit） is mostly based on practical experience, combined with trial and error method, repeated design calculations, low design accuracy, long cycle, difficult to improve design quality, only one can be designed according to calculation, low efficiency. The tricone bit（rotary cone bit） is an important tool for oil drilling, and its performance will directly affect the drilling quality, drilling efficiency and drilling cost. Tricone drill bit is one of the widely used drill bits, which has the characteristics of adapting to the width of the formation and high ROP. The tri-cone bit is composed of more than 20 parts such as cutting structure, bearing structure, locking element, oil storage and sealing device, and nozzle device.
Classification of tricone bits:
1. Bearing type: rolling bearing and sliding bearing
2. Sealing method: rubber seal and metal seal
3. According to the fixing method of the teeth, it is divided into: insert (hard alloy teeth) tricone bits（rotary cone bit） and milling (steel teeth) tricone bits
During the use of the tricone bit, the mud quality should be kept as clean and hygienic as possible to avoid the problem of water eye blockage at the bit. At the same time, the normal use of the bit can also be guaranteed to a certain extent. We must also control its drilling speed. Do not adjust the speed of the drill bit too fast. Because if the speed is modulated too fast, if you encounter resistance suddenly, the degree of damage will be greatly increased. It is impossible for the drill bit to exert its excellent performance. And it is necessary to keep the bottom of the well clean and tidy, do not pile too much debris in it, and pay attention to avoiding problems such as slipping and bumping of the drill bit during use.
