Functions and features:
1. The service life of the bit is longer than that of cemented
carbide and 4-5 times of that of ordinary diamond bit;
2. High drilling efficiency: the diamond outcrop is large (almost
all the composite polycrystalline layers are exposed), and the bit
can always keep sharp, thus greatly improving the footage speed;
3. It can drill with low pressure and low rotation speed: the bit
breaks the rock by scraping and shearing, and its WOB only needs
about 1 / 3 of that of the impregnated diamond bit of the same
diameter;
4. Good diameter protection effect: diamond polycrystalline can be
inlaid inside and outside of the drill bit of our factory, which
has strong wear resistance and good diameter maintenance
performance, It has been proved that the bit is suitable for
drilling soft and medium hard strata (with drillability below grade
9) such as carbonate rock, limestone, Cretaceous, clay rock,
siltstone, sandstone and so on. Compared with the general bit,
especially in the 6-9 rock stratum, the effect is particularly
remarkable;
6. Because of its high penetration rate and long service life, the
number of trips and trips is less, the drilling cost is greatly
reduced, and the performance price ratio is superior.
