When choosing to buy drill pipe products, we need different style different material of drill pipe to a specific classification, the PDC bit, diamond bit and some other apart from the rest of the class of drill pipe products, such ability can accurate price comparison for different material of the structure of the products, have their own different pricing rule, but either way drill tools, drill pipe rigid hierarchy, will directly affect the price of high and low, if the drill pipe level of rigidity of the strong, has the strong ability of bending, the price will be increased. Then, since the rigidity of the drill pipe will affect the price, we do not need to choose the products with higher rigidity, we need to choose the rigidity of the drill pipe according to the place where drilling tools are often used.
While drilling tools are in use, many believe that the drill bit is the most vulnerable because the DPC bit bears the brunt of formation impact and pressure. But in fact, the drill pipe is also subject to a lot of pressure, not only will be subjected to upward resistance, but also the friction around is also very large, so we need to choose different types of drill pipe according to different strata.
If you want to improve the bending ability of the drill pipe, you must choose the material and structure of the drill pipe compared with the place of use, choose the drill pipe products that are more suitable for a certain environment, so as to protect the geological drill pipe, or other drill pipe, from excessive pressure or impact.
