The functions of lubricants in diamond drilling were discussed in this paper. The influences of lubricant on drilling efficiency
and bit’s life were compared and analyzed with simulated drilling test and lubrication test apparatus. Lubricating mechanisms
were also discussed.
Key words lubricating drilling fluids - diamond bit - drilling pressure
