EXPERIMENTAL RESEARCH ON THE WEAR OF DIAMOND BIT IN HIGH RPM DRILLING

Duan Longchen Tang Fenglin (Engineering Faculty,China University of Geosciences,Wuhan,430074,China)  
This paper has discussed the increase of penetration rate and the decrease of bit wear in diamond bit drilling with a high rotation speed.It has made an approach to the relation between the two technical indexes and the drilling pressure and the rotation.It has presented the index of drilling efficiency expressed by the ration of penetration rate and matrix wear,this determing the optimal drilling parameters based on the latter index.
