随着海洋地质科学的迅速发展,已有的钻探取芯手段已不能满足海洋地质工作进一步发展的需要。因此,海底钻探技术的研究已成了海洋科学领域的一个重要课题。 目前,国内外所采用的海底钻探技术设备在类型、经济和性能方面都很不相同。美国在六十年代为了执行《深海钻探计划》而建造了 With the rapid development of marine geosciences, the existing drilling coring means can no longer meet the needs of further development of marine geology. Therefore, the research of subsea drilling technology has become an important issue in the field of marine science. At present, the subsea drilling technology equipment adopted at home and abroad is very different in terms of type, economy and performance. The United States was built in the 1960s to implement the Deepwater Drilling Program
