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。
切削齒佈齒設計是PDC鑽頭設計的關鍵。為提高PDC鑽頭的鑽進效率,綜閤攷慮PDC鑽頭切削齒的設計特點和切削先後順序等因素,併且通過對PDC鑽頭單切削齒實驗結果進行分析,提齣瞭以冠部輪廓法線為基準的切削齒佈齒設計方法。
절삭치포치설계시PDC찬두설계적관건。위제고PDC찬두적찬진효솔,종합고필PDC찬두절삭치적설계특점화절삭선후순서등인소,병차통과대PDC찬두단절삭치실험결과진행분석,제출료이관부륜곽법선위기준적절삭치포치설계방법。
Cutting teeth arrangement is the key of PDC rock bit design, in order to improve the drilling efficiency, the de-sign 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.
