摘　　要：在总结分析国内外有关PDC切削齿性能测试方法的基础上,采用常规检测方法对不同生产厂家的5种PDC产品的磨耗比、冲击韧性和热稳定性进行测试、评价和优选,并对优选出的2种PDC在微钻试验平台上进行实钻性能测试。结果表明:用微钻试验的钻进效率衰减系数和钻进效率均峰值来评价PDC实钻性能,方法科学,数据准确,结果实用,可作为煤矿用PDC钻头切削齿选型的参考依据。Based on summarizing and analyzing the PDC performance testing methods at home and abroad,the wear ratio,impact toughness and thermal stability of five PDC products of different manufacturers were tested,evaluated and optimized by conventional testing methods.The actual drilling performance test was carried out on the micro drilling test platform with the two selected PDC bits.The results show that the drilling efficiency attenuation coefficient and the average peak value of drilling efficiency are used to evaluate the PDC real drilling performance.The method is scientific,the data is accurate and the result is practical.It can be used as the reference basis for selection of PDC bit teeth for coal mine drilling.
