摘　　要：在聚晶金刚石复合片钻头的钻进过程中,其钻进效率受到很多因素的制约。考虑钻头切削角度、切削速度和钻进速度对钻进过程的影响,利用LS-DYNA对聚晶金刚石复合片钻头钻进岩层的过程进行了模拟。通过仿真计算建立了聚晶金刚石复合片钻头切削角度的变化与钻进效率之间的关系,比较分析了切削速度和钻进速度对钻进过程的影响。Drilling efficiency of Polycrystalline Diamond Compact Bit was constrainted by many factors during the drilling process.With respect to the effect of the cutting angles,cutting speed and drilling speed on the drilling process,this paper simulated the drilling process of PDC bits by the use of a well-known finite element package,LS-DYNA.Based on the results of analysis,the relationship curve between the change of cutting angle and the drilling efficiency has been established,and the author also analyzed the influence of the drilling process,which responde to the change of cutting angles and cutting speed respectively.
