There are mainly two types of drill bits, roller cone bits and diamond bits, and Huaying is one of the domestic companies that produce these two types of bits. The roller cone bit is the most widely used traditional drill bit in oil drilling. The amount of work completed by the roller cone in oil and gas drilling accounts for about 80%-90%. Industry insiders pointed out that drill bits are a necessity and consumable in the process of LPG drilling and production, accounting for about 4% of drilling costs. The future growth of investment in oil and gas exploration will inevitably drive the growth of demand for drill bits.Petroleum exploration and drilling equipment mainly refers to special equipment for oil and gas exploration, drilling, development, storage and transportation, including various types of geophysical prospecting and logging equipment, drilling equipment, oil and gas production equipment, downhole operation equipment, oil and gas gathering and transportation equipment, and offshore drilling equipment. Platform equipment, etc. and related accessories and tools. At present, most of these equipment have certain domestic capabilities, and many listed companies have participated in it.It can be seen from the application dynamics developed on the gage structure of the Reaming Bit that the gage structure has a very large impact on the drill bit\u2019s ROP and life, mainly in the use of directional and horizontal wells. The drill gauge structure has achieved good results in the application of roller cone bits. The materials used in the gauge are many wear-resistant composite materials. The gauge structure of the drill bit has developed from passive gauge to active gauge. The structure and materials of the gauge have been improved to improve the performance of the drill bit. Improve the drilling speed and life of its machinery. There are some gaps in the research and development of gauge structures and materials at home and abroad. There are also research and development institutions and manufacturers in China who pay attention to the application of some active gauge structures in their research, and further improve the production of roller cone bits in China. The resulting effect provides our users with highly efficient drill bits with very good new drilling technology.Whether it is a soft formation or a hard formation, the cooperation of roller cone bits is needed to better promote the drilling work. It is not difficult to find that, in fact, we often use reaming bits in drilling. For a long time, everyone's improvement of the cutting layout mainly focused on the layout of the main cutting teeth. Because in the past ten years, everyone has gradually realized that the gauge layout also has a greater impact on the ROP and life of the drill bit, especially in the demand for the drill bit used in highly deviated wells and horizontal wells. Diameter layout, many new gage layouts have been researched and developed and have been used on roller cone bits to achieve excellent effects.
