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, it can be divided into steel teeth (milling teeth) and insert roller bits.
The roller cone bit has been widely used as a tool for drilling rock formations. Significant improvements in drill performance directly reduce drilling costs, especially in the last decade. Two performance indicators, service life and drilling speed, which ultimately determine the extent to which the drill bit affects drilling costs. Increasing the drilling speed and service life of the drill bit is an effective way to reduce the drilling cost. It is confirmed by the data that the improvement of the drilling speed is more important than the improvement of the life of the drill bit to reduce the drilling cost. The improvement of the cutting structure of the drill bit is to improve the mechanical mechanism of the drill bit. The most direct method of drilling speed. For a long time, the improvement of cutting structure has mainly focused on the main cutting tooth structure. For example, in the case of cemented carbide tooth structure, wedge tooth, spoon tooth, partial spoon tooth, and other wear teeth have been invented. . It is gradually recognized that the gauge structure also has a great influence on the drilling speed and life of the drill bit. Especially in the case of high-angle wells and horizontal wells, the drill bit requires a reasonable diameter-preserving structure, and many new-type gauge structures have been researched and developed. Good results have been achieved when applied to roller cone bits.
It can be seen from the research and application dynamics of the drill bit manufacturer and the research institute in the three-cone bit diameter-preserving structure that people have gradually realized that the gauge structure has a great influence on the drilling speed and life of the drill bit, especially in the directional well and horizontal well application. The impact of the larger, research and development of the new drill bit diameter structure has achieved good results in the application of roller cone bits. The drill bit diameter structure has evolved from passive gauge to active gauge. The gauge material has evolved from low wear resistant material to high wear resistant composite material. The improvement of drill bit diameter structure and material has greatly improved the performance of the drill bit and further improved the drill bit. Mechanical drilling speed and life. There are certain gaps in the research of the structure and materials of the gauges at home and abroad. The relevant domestic research institutes and manufacturers of drills should further strengthen the research on the structure and materials of the gauges, especially focusing on the research and application of some active gauge structures in the drill bit to further improve the domestic teeth. The performance of the wheel bit provides the drilling user with a high-efficiency drill bit that adapts to the new drilling process.
The most widely used in oil drilling and geological drilling is the roller bit. The roller bit has the function of impact, crushing and shearing to break the formation rock when it is rotated. Therefore, the roller bit can adapt to various layers of soft, medium and hard. Especially after the emergence of the jet cone bit and the long nozzle cone bit, the drilling speed of the roller bit has been greatly improved, which is a major revolution in the development history of the cone bit. According to the type of teeth, the roller cone bit can be divided into milling gear (steel tooth) roller cone drill bit, insert tooth (carrying carbide tooth on the cone), roller cone drill bit, and can be divided into single cone drill bit and three teeth according to the number of cones. Wheel bit and assembly multi-cone bit. The most widely used and most commonly used is the tri-cone bit.
