Tricone Bit are suitable for hard formation drilling effectively and safely.
Characteristics:
-The bit has structure features of metal face sealed and enhanced head O.D.for drilling in hard formations.
-The bit has the advantages of long service life,high reliability,fast ROP and strong gage protection ability etc..
PDC Bits are suitable for medium and medium hard formations.
Characteristics:
-Specific to characteristics of hard formation and interbeded formation,bit profile is optimized and cutting depth of the bit is controlled.
-Overall performance of PDC cutter is improved by using high performance PDC cutters of better wear resistance, better impact strength and better thermal stability.
-Unique cutter layout and specific force balance analysis plus other related technologies,etc.improved the bit's working life and premature ring type wear of the bit is prevented.
-Optimized hydraulic design can improve the bit's cooling effect and therefore, prevent PDC cutter failure caused by high temperature.
-Bit diameter shringage is effectively prevented by enhanced gage protection desig.
