摘要
为了提高钻头破碎岩石的速度和使用寿命,把仿生非光滑理论和PDC钻头切削齿的结构设计制造理论和技术相结合,以提高PDC齿对岩石的攻击力和其自身的耐磨性。通过测试数据分析,得出仿生PDC切削齿比普通切削齿的耐磨性高,攻击力强。本文把仿生学在钻探中的应用范围再次拓宽,相信在不久的将来仿生PDC切削齿将成为钻探碎岩的又一新利器,为更加高效的钻探技术打下基础。
In order to improve the speed and service life of rock breaking bits,the bionic non smooth theory and the structure design and manufacturing theory and technology of PDC bit cutting teeth are combined to improve the PDC bit’s attack on rock and its own wear resistance.Through the analysis of test data,it is concluded that bionic PDC cutting teeth have higher wear resistance and stronger attack power than ordinary cutting teeth.This paper expands the application scope of bionics in drilling again,and believes that in the near future,bionic PDC cutting teeth will become another sharp tool for drilling broken rock,laying the foundation for more efficient drilling technology.
