PDC钻头切削齿布齿设计的新思路

New Idea of Cutting Teeth Arrangement Design for PDC Rock Bit

摘要:

切削齿布齿设计是PDC钻头设计的关键。为提高PDC钻头的钻进效率，综合考虑PDC钻头切削齿的设计特点和切削先后顺序等因素，并且通过对PDC钻头单切削齿实验结果进行分析，提出了以冠部轮廓法线为基准的切削齿布齿设计方法。

Abstract:

Cutting teeth arrangement is the key of PDC rock bit design， in order to improve the drilling efficiency, the design features of cutting teeth of PDC bit, the cutting order and some other factors are taken into account; by the analysis on the experimental results of PDC bit single tooth, a new design method of cutting teeth arrangement is put forward, which is based on crown surface normal line.
