人造金刚石钻探,是在无产阶级文化大革命期间发展起来的一项新技术.在毛主席“独立自主,自力更生”的伟大方针指引下,各有关单位团结协作,克服了重重困难,研制、试验成功了人造金刚石钻头,并在钻进工艺等有关技术环节上取得了新的进展或突破.随着人造金刚石钻探技术的逐步推广,必将促进冶金地质钻探面貌的大改观.从而加快冶金资源勘探的速度;由于钻头用的是国产人造金刚石,作为这项新技术基础磨料的金刚石的需求,就可以完全立足于国内,所以说,人造金刚石钻探技术的试验成功,是有其政治意义和经济意义的.为了逐步推广这项新技术,冶金部于一九七四年十至十一月举办了人造金刚石钻探学习班,由中南矿冶学院、长春冶金地质学校、中南冶金地质勘探公司和桂林冶金地质研究所提供教材和参加讲课.本刊辑录、整理了这一教学讲义,编入《钻探讲座》,拟于一九七五年内逐期刊登.希望广大读者阅后随时提出宝贵意见或要求,以便据以改进.使我们尽可能地作好这项新技术的普及工作.
Artificial diamond drilling is a new technology developed during the Great Proletarian Cultural Revolution and under the guidance of Chairman Mao’s great principle of “independence and self-reliance”, all relevant units worked together to overcome difficulties and develop and test successfully Artificial diamond drill bit, and drilling technology and other related aspects of technology has made new progress or breakthrough.With the gradual promotion of artificial diamond drilling technology, metallurgical geological drilling will certainly promote the appearance of a major change.To accelerate the exploration of metallurgical resources Speed; as the drill is made of domestic synthetic diamond, diamond as the basic technology of this new technology needs can be completely based on the domestic, so that the artificial diamond drilling technology test success is of political and economic significance In order to promote this new technology step by step, the Ministry of Metallurgical Affairs held a seminar on artificial diamond drilling from July to November 1974. The seminar was co-sponsored by Zhongnan Mining and Metallurgical Institute, Changchun Metallurgical Geological School, Zhongnan Metallurgical Geological Exploration Company and Guilin Metallurgical Geology Institute to provide teaching materials and participate in lectures .In this journal, compiled the teaching notes, into the “drilling Lecture ”is scheduled to be published in a periodical manner in 1975. We sincerely hope that readers can make valuable suggestions or requests at any time after reading it so as to make improvements so that we can make the best use of this new technology as soon as possible.
