有关金刚石钻进原理的研究

Study on the principle of diamond drilling

结合试验研究及国内外经验，提出以控制钻头切入量为准的钻进规范，获取最优化钻进；依据增大切入量原则，分析论述研究优质大粒聚晶体的必要性和可能性，突破现用金刚石钻进的局限；分析了当前专业技术状况，提出加强科学试验和研究的重大意义。

Based on our research study and experiments abroad ,propose drilling role being con-trolled with standard of cut-in depth of bit.to getoptimization in drilling. Based on the principle ofcut-in depth of bit.discuss the necessity and possi-bility to made polycrystalline diamond inserts with execellent properties for drilling,to break through the limitation of recent diamod drilling. After analysing the situation of recent speciality tech- nique,put forward the important significance to en- hance the scientific research work.
