What changes have taken place during the PDC bit modification?(圖1)

In PDC drill bit has just appeared in drilling operation, compared with some other material of drill bit is not able to achieve a better use effect, so cause the bit type or material can't was welcomed by more people, will not be able to achieve a better effect of drilling, so the PDC bit in recent years continued to shape the improvement, continuously to make materials selection, the bit of products introduced in recent years, compared to the past, to produce PDC bit to achieve a better effect.


Firstly, the external structure of PDC bit has changed, and the shape of the teeth has slightly changed, which has a great influence on the effect in the process of use. However, it also provides a better buffer force for the bit in the process of operation, so as to ensure a smoother effect in the process of use. And then there is the material of drill bit has changed, which directly affects the status of classification of PDC bit in the drill bit, drill bit more hard material, so in operation process can effect in different strata, has a greater impact, then not only suitable for soft rock strata, will also be able to function in the hard rock, using range has expanded, thus improve the effect of the use of PDA bit in the middle of the invisible.
