采用金刚石钻头钻进硬材料(象硬岩层)时,决定钻进效率的一个重要因素是金刚石的磨损速率。磨损使锋利的切削刀钝化,从而钻进速率就会降低。然而人们很少注意用分析函数来描述这种磨损过程,尽管它具有潜在的功用。例如:钻进的变化因素(转速、压力等)对磨损参数的影响,能有助于进一步理解磨损过程本身的特征。在实际工作中该函数也能用来预测在钻探过程中钻头的寿命。Tsoutrelis在早些时候曾提出过一种合理的分析函数,来描述金刚石钻头的磨损对岩层进尺(即钻进深度)的影响。然后在 Diamond drill bit drilling hard materials (such as hard rock layer), determine the drilling efficiency is an important factor is the diamond wear rate. Abrasion sharpens the sharp cutting blade, so the drilling rate is reduced. However, people pay little attention to using analytic functions to describe this wear process, although it has potential utility. For example: The impact of drilling variations (speed, pressure, etc.) on the wear parameters can help to further understand the characteristics of the wear process itself. In practice, this function can also be used to predict the life of a drill bit during drilling. Earlier Tsoutrelis had proposed a reasonable analytical function to describe the effect of diamond bit wear on the footage footage (ie, the depth of drilling). Then at
