75mm Wireline single tube impregnated diamond core bit for rock
sample drilling
Impregnated diamond core drill bit
The diamond core bits cutting ability has been developed to allow
high penetration rate base on different formation. The combination
of crown shape,hardness and water way have increase drilling
performance on broad range of formations.
Drilling recommendations
To select a suitable diamond bit for a given situation, basic
information is needed:
* Geology
* Type and size of core barrel
* Flushing media
The final performance with selected bit depends on following
parameters controlled by the operator:
* WOB – weight on bit
* ROP – rate of penetration
* RPM – revolution per minute
* RPI/RPC – revolution per inch/cm
* Flushing
