绳索取心钻进的突出优点在于少提钻具,减少辅助时间,提高纯钻时间,从而较大幅度提高了钻进效率,减轻劳动强度.因此,许多国家广泛采用了这种工艺技术.我国自七十年代初将人造金刚石应用于地质岩心钻探取得成功后,金刚石钻进技术得到了迅速发展.近年来,随着人造金刚石质量的提高,金刚石钻头性能的不断改善,钻头寿命也得到较大提高,同时,管材钻具的研究也取得了新的进展,从而为绳索取心钻进 The prominent advantages of rope coring drilling lie in less mention of drilling tools, less auxiliary time and higher pure drilling time, which greatly improves the drilling efficiency and reduces the labor intensity, therefore, this kind of process technology is widely adopted in many countries. Diamond drilling technology has been rapidly developed since the early 1970s when synthetic diamond was applied to geological core drilling. In recent years, with the improvement of the quality of synthetic diamond and the continuous improvement of the performance of diamond drill, the life of the drill bit has also been larger Increase, at the same time, pipe drilling research has also made new progress, so as to coring the rope
