APPLICATIONS OF DIAMOND DRILL BITS WITH HIGH PERFORMANCE TURBODRILLS

Sergey L.Simonyants –  PhD in Engineering, professor the Gubkin University of Oil and Gas, ssturbo@mail.ru.
Ivan V. Mnatsakanov – candidate for a degree, Smith Int.

Key words: impregnated diamond drill bits, turbodrill, hard abrasive rocks.

Impregnated diamond drill bits are effective rock cutting tools to drill hard abrasive formations. The best drive mechanism for these drill bits are high speed turbodrills whose mechanical output is increased by new high torque turbines. Further testing of the impregnated diamond drill bits with high performance turbodrills will enable to establish the most effective parameters of turbine drilling in different geological environments.
