摘要
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。
Drawn upon the experiment and the experience home and abroad, the drilling criteria which is based on the control of the bit penetration amount is proposed to achieve optimum drilling performance. According to the principle of increasing the penetration value, it is necessary and possible to develop quality large size PCDs so as to transcend the limitation of existing diamond drilling. The status quo of the technique is reviewed, and the significance of beefing up scientific experiment and research is emphasized.
