我队推广SC-56绳索取芯技术已经两年了，现开动二台，截至80年底止，共打完11个钻孔，总进尺6000余米，孔深多在500—600米间。用SC-56绳索取芯钻具施工千米深孔，是我队80年钻探技术上的一个突破。通过千米深孔的施工实践，进一步证明了绳索取芯的优越性，同时检验了钻具的性能、结构合理程度，也暴露了一些问题，为进一步完善钻具结构提供了资料。
Our team has promoted SC-56 rope coring technology for two years and now it has started two sets. As of the end of 1980, a total of 11 holes have been drilled, with a total footage of 6,000 meters and a hole depth of 500-600 meters. With SC-56 rope coring drill construction of deep hole, is my team 80 years of drilling technology breakthrough. Through the practice of 1000-meter deep hole, the superiority of rope coring is further proved. At the same time, the performance of drilling tools, the reasonable structure and the problems have also been exposed, which provide the materials for further improving the structure of drilling tools.
