在一些冶金地质勘探队,已开始使用一种钻探新工具——端管器。这是一项较好的技术革新经验。《地质与勘探》1964年第4期,于“106队在钻探施工中推广使用的一些技术革新经验”一文中,曾将端管器作了简要的介绍,现在我们拟对它的结构和作用原理,作进一步说明,供同志们参考:端管器是在1959—1960年间,由吉林某勘探队孙洪蔭同志提出,经过其所在机台的全体同志不断研 In some metallurgical geology exploration teams, a new tool for drilling has been used - the pipe end. This is a good experience in technological innovation. “Geology and Exploration”, No. 4, 1964, in the article “Some of the Technological Innovation Experiences Used by the 106th Team in Drilling Construction”, has briefly introduced the end effector, and now we propose its structure and function. Principles, for further explanation, for comrades to refer to: the end of the pipe is between 1959-1960, proposed by Comrade Sun Hongyin of a certain exploration team in Jilin, through all the comrades on its platform continued research
