【摘要】 热熔法是一种全新的碎岩方法，在南极中深孔的钻进中起了重要作用。通过对前苏联、美国、法国、日本等国热熔钻具的分析，提出了南极冰钻热熔钻具的合理组成系统及各部分功能。重点阐述了俄罗斯ТБЗС－１５２Ｍ钻具结构特点、使用效果及护壁液的成分和性能。更多还原

【Abstract】 Hot melting is a completely new method to fracture rocks and has played a very important role in drilling medium deep and deep holes in Antarctic area. Based on the analysis of thermocorers developed by scientists from former USSR, USA, France and Japan, this paper presents a reasonable system for drilling Antarctic ice layers and the functions of each of its elements. The structural characteristics and the results of application of the Russian ТБЗС 152M thermocorer and the properties and composition of the wall protecting fluid are discussed in more defail更多还原
