摘　　要：该文介绍了几种石油钻头用金刚石烧结体耐磨性的测试方法,着重分析了磨耗比测试方法的不可靠性,并提出一种采用均质花岗石和近于钻井实际的试验条件来测定烧结体耐磨性的新方法。In this paper are presented some methods for measuringthe wear resistance of PCD used in petroleum drilling bits. whileanalysing the unreliability of the 'wear ratio method', the authorspropose a new measuring approach which involves cutting a block ofhomogeneous granite with PCD, such case is more approximate to thepractical petroleum drilling.
