Drilling Technology and Strategy Used in Continental Scientific Drilling

摘要:

国外实施大陆科学钻探采用的钻探技术有地质岩心钻探技术、石油钻探技术、组合式钻探技术 ,以及前苏联和俄罗斯的具有鲜明特色的科学深钻技术 ,分别介绍了它们各自的技术特点及优缺点 ,并介绍了科学深孔和超深孔的 2种施工战略 ,即超前孔裸眼钻进方法和双孔方案。

Abstract:

The mainly used drilling technology in continental scientific drilling oversea includes geological core drilling technology, petroleum drilling technology, and hybridizing technology as well as the technology used in former Soviet Union and Russia. The advantages and disadvantages of the technology mentioned above were introduced. Two types of drilling strategy for deep and super deep bore hole, that is advanced open hole drilling method and double hole method, were also presented.
