What are the ways to distinguish the quality of diamond bits
There are many types of diamond drill bits, such as diamond composite drill bits and diamond core drill bits. The quality of their quality is the most concerned issue of the mining personnel. Good drill products can help the mining personnel to complete the work smoothly, so everyone wants to buy them. High-quality drill products, improve the service life of the drill!
Diamond drill bits refer to watch and impregnated drill bits made of natural diamond, synthetic diamond, composite sheet, sintered body, polycrystalline, etc. as cutting tools. The entire drill bit has no moving parts and has a relatively simple structure with high strength, high wear resistance and impact resistance. It was one of the three new drilling technologies in the world in the 1980s. It is the most advantageous helper for mining! Diamond drills have the advantages of high speed, large footage, long life, stable work, fewer underground accidents, and good well quality when drilling in soft-medium-hard formations. Diamond drill bits are not only used for a long time, but can also be reused. The use effect of the returned diamond drill bit is similar to that of the factory diamond drill bit, which can save a lot of drilling costs. Because of these characteristics, the diamond drill bit market is very good now, but buyers should pay more attention to it when purchasing, and analyze what kind of diamond bit is of good quality and what is of poor quality.
The quality of the bit, whether the bit type and the formation lithology are suitable, play an important role in accelerating the drilling speed and increasing the footage of a single bit. Drilling an oil and gas well generally uses multiple drill bits of different sizes. When drilling the upper strata, use a larger diameter drill bit. Because the drill bit drills into the ground is softer, a single drill bit has a large footage and a short use time. One bit is generally Several wells can be reused; and a smaller diameter drill bit should be used when drilling the lower stratum. Because the formation is hard and the footage of a single drill bit is small, multiple drill bits are generally used. The drilling footage of a new drill bit mainly depends on the size and type of the drill bit, the softness and hardness of the formation, and the coordination of drilling parameters. Generally speaking, the smaller the size of the drill bit and the harder the formation, the less the footage; the larger the size of the drill bit and the softer the formation, the more the drill footage will be.
