As a tool for drilling rock formations, cone drills have been widely used. Significant improvements in drill performance have directly reduced drilling costs, especially the fastest progress in the past decade. Service life and drilling speed Performance indicators, they finally determine the degree to which the drill bit affects the cost of drilling. Increasing the mechanical drilling speed and service life of the drill bit is an effective way to reduce the cost of drilling. Some data have confirmed that the improvement of the drilling speed than the improvement of the life of the bit has an effect on reducing the cost Larger, in which the improvement of the cutting structure of the bit is the most direct method to increase the mechanical drilling speed of the bit.

used tricone roller bit for sale  in China For a long time, the improvement of cutting structure is mainly focused on the main cutting tooth structure.For example, in terms of carbide tooth structure, people have invented wedge-shaped teeth, spoon-shaped teeth, partial Spike-shaped teeth, equal wear teeth, etc. In the past ten years, people have gradually realized that the diameter-retaining structure also has a greater impact on the mechanical drilling speed and life of the bit, especially in high-angle and horizontal wells. The structure of many kinds of diameter-retaining structures has been researched and developed and applied to roller cone drill bits, and has achieved good results.
