西西伯利亚地质联合体是在1976年进行煤田勘探时掌握使用KCCK-76和CCK-59型绳索取心钻具的,应用这种钻具提高了劳动生产率25—30％,降低了金刚石的消耗,提高了取样质量,并改善了钻探人员的劳动条件。从1977年起,库兹巴斯的绳索取心钻进工作量迅速增加,如1977年为总工作量的2.6％,到1983年已达36％,到第十一个五年计划末,计划钻进的绳索取心钻孔将占70％。绳索取心钻具各部件和零件的结构,简单而可靠。但由于综合性能不适用煤田复杂地质构造钻进,西西伯利亚地质联合体勘探技术方法试验队,为了在库兹巴斯条件下使用KCCK-76和CCK-59型钻具,对其作了结构方面的改进。改进后的钻具顺利通过了生产试验。图
The West Siberia Geological Consortium mastered the use of KCCK-76 and CCK-59 cord coring tools when drilling coal in 1976. The use of such tools increases labor productivity by 25-30%, reduces diamond consumption, Improved sampling quality and improved driller’s working conditions. From 1977 onwards, Kuzbass’s rope coring drilling workload increased rapidly. From 1977 to 2.6% of the total workload, it reached 36% by 1983. By the end of the eleventh five-year plan, plans Coring holes drilled into the rope will account for 70%. The structure of each part and part of rope coring drilling tool is simple and reliable. However, due to the inability of complex properties to drill into complex geological formations in coalfields, the West Siberian Geological Exploration Technology Methodological Experiment Team made structural aspects for using KCCK-76 and CCK-59 drilling tools under Kuzbass conditions improvement of. The improved drilling tool successfully passed the production test. Figure
