Tricone Roller bit is the most widely used drilling bit. When the roller cone bit is working, the cutting teeth alternately contact the bottom of the well, the torque of breaking the rock is small, the contact area between the cutting tooth and the bottom of the well is small, the specific pressure is higher, and it is easy to eat into the formation; the total working length of the working blade is large, thus relatively reducing the wear. Roller bit can adapt to a variety of formations from soft to hard.

According to the number of cones, it can be divided into single-cone bit, tri-cone bit, and assembled multi-cone bit. According to the cutting material can be divided into steel teeth (milled teeth) and insert tooth bit.

The Tricone roller cone bit has been widely used as a tool for drilling rock formations, and a significant improvement in the performance of the bit directly reduces the cost of drilling, especially in the last ten years. The two performance indicators, life time and drilling speed, ultimately determine the extent to which the drill bit affects drilling costs. Raising the penetration rate and service life of the drill bit is an effective way to reduce the drilling cost. It is verified by the data that the improvement of the drilling speed is more effective than the improvement of the bit life to reduce the drilling cost. The improvement of the cutting structure of the drill bit is to improve the drilling machine's machinery. The most direct method of drilling speed. For a long time, people's improvement of the cutting structure mainly focused on the main cutting tooth structure. For example, in the cemented carbide tooth structure, people have successively invented wedge-shaped teeth, spoon-shaped teeth, partial-topped spoon-shaped teeth, and other wearable teeth. . People gradually realized that the gauge structure also has a great impact on the penetration rate and life of drills. In particular, the drill bit used in high-angle wells and horizontal wells requires a reasonable diameter-preserving structure, and many new gauge structures have been researched and developed. Applied to the roller cone bit has achieved good results.
