Wide - ranging formation adaptability:
Tricone bits can adapt to various types of formations. Whether it is soft formations (such as clay, shale, sandstone, etc.), medium - hard formations, or hard formations, they can maintain relatively good drilling performance. This makes them highly applicable in areas with complex geological conditions or regions with alternating formations, reducing the frequent replacement of bits due to formation changes and improving the efficiency and economy of drilling.

 

Higher rate of penetration (ROP):
Under the action of bit weight and drill string rotation, the teeth of the tricone bit can impact, crush, and shear the rock. This composite rock - breaking method enables it to have a higher rate of penetration. Especially after the emergence of jet tricone bits and long - nozzle tricone bits, the drilling speed has been further improved, greatly shortening the drilling cycle.

 

Longer service life:
The structural design of tricone bits is relatively reasonable. It consists of more than twenty components such as cutting structures, bearing structures, locking elements, oil - storage sealing devices, and nozzle devices. The various components cooperate with each other and can withstand relatively large bit weights and torques. At the same time, some high - quality tricone bits adopt high - quality materials and advanced manufacturing processes, which improve the wear resistance and corrosion resistance of the bits, thereby prolonging their service lives. For example, insert - type tricone bits use high - strength and high - toughness cemented carbide teeth, which have high wear resistance and excellent cutting ability and can work for a long time in harsh drilling environments.

 

Good bottom - hole cleaning ability:
During the rotation of the tricone bit, the rolling of the cones and the cutting action of the teeth can effectively break the rock debris at the bottom of the well and carry it to the surface, keeping the bottom of the well clean. Good bottom - hole cleaning ability helps to reduce the repeated crushing of the bit, improve the drilling efficiency, and at the same time can reduce the probability of accidents such as stuck pipes caused by the accumulation of cuttings at the bottom of the well.

 

Higher stability and reliability:
The three cones of the tricone bit form a stable support structure at the bottom of the well, making the bit have higher stability during the drilling process and being able to maintain a good drilling direction and trajectory. In addition, the tricone bit has relatively good sealing performance, which can effectively prevent the leakage of drilling fluid and the entry of impurities into the bit, ensuring the normal operation of the bit and improving the reliability of drilling.

 

Precise drilling control:
The tricone bit can precisely control the working state at the bottom of the well. Operators can adjust parameters such as bit weight and rotation speed according to the needs of drilling to achieve the best drilling effect. This precise drilling control helps to improve the quality of drilling and reduce problems such as well deviation and wellbore collapse caused by improper drilling parameters.

 

Good economy:
Although the initial purchase cost of tricone bits may be relatively high, due to their long service life and high drilling efficiency, they can reduce the total cost of drilling in the long - term use process. Especially in some large - scale drilling projects, the economic advantages of tricone bits are more obvious.
