一年一度的辞旧迎新,我门广大探矿工作者又以优异的成绩迎来了建国后的第三十七个春天,以矫健的步伐跨入了“七五”计划第一个年头。在新的一年到来之际,回顾已走过的路程,我感到在钻探生产技术上还有一些值得探讨的问题,在这里提出个人的初浅看法,与同行们商榷。一是关于金刚石钻头选型和综合效果问题。现在已较普遍地出现了广泛选用各厂家钻头和积极采用人造金刚石钻头的好势头。但我感到要防止片面性和绝对化。选型的目的是求得钻头与岩层相适应,从而达到高效、长寿和低成本。单纯为提高钻头寿命或降低单个钻头价格,忽视钻头与岩层的适应性和综合效
The annual greetings and greetings by the general public have welcomed the 37th spring after the founding of the PRC with excellent achievements and stepped into the first year of the Seventh Five-Year Plan with vigorous strides. As the new year is approaching, I have reviewed the journey I have taken. I feel that there are some issues worth exploring in the area of drilling production technology. I hereby put forward my personal initial thoughts and discuss with my colleagues. One is about diamond bit selection and the overall effect of the problem. It is now quite common to see the widespread adoption of drill bits from various manufacturers and the aggressive use of synthetic diamond bits. But I feel I should prevent one-sidedness and absolute. The purpose of selection is to find the drill bit and rock adaptation, so as to achieve high efficiency, long life and low cost. Simply to enhance the life of the drill bit or reduce the price of a single bit, ignoring the drill bit and the adaptability of strata and comprehensive effect
