在批林批孔运动深入、普及、持久发展的大好形势下，为了配合推广金刚石小口径钻进，根据国家计委地质局的指示，由地质科学院勘探技术研究所、无锡探矿机械厂和西南地质科学研究所共同组成了“绳索取心钻进方法研究试制小组”。经过研究，设计和加工，于一九七四年五月试制成功我国第一台小口径金刚石岩心钻进的S56绳索取心钻具。之后，又同北京市地质局协作，共同组成钻具试验小组，于七月下旬在该局102队507机台Zk2号钻孔进行了钻具性能试验。试验钻具总进尺为36米（试验孔段185—
Under the favorable situation of deepening, popularizing and lasting development of bore hole bored movement, in line with the promotion of small-diameter diamond drilling, according to the instructions of the State Planning Commission Geological Bureau, the Institute of Exploration Technology of Academy of Geological Sciences, Wuxi Prospecting Machinery Factory and Southwest Geology Institute of Science jointly formed a “rope coring drilling method research trial team.” After researching, designing and processing, the S56 rope coring drilling tool successfully drilled in China’s first small-diameter diamond core was successfully trialled in May 1974. After that, they collaborated with the Beijing Bureau of Geology to form a drilling and drilling test group. Drilling performance tests were carried out at Zk2 No. 507 drilling station of the 102th station in late July. Test drilling total footage of 36 meters (test hole 185-
