| 中文摘要:地球科学的发展对地球深部数据的依赖程度越来越高,作为“入地”重要手段的科学超深井工程是研究深部地质学的重要方法，被誉为是“伸入地壳的望远镜”。与钢钻杆相比，铝合金钻杆以其独特的优越性(质量轻、比强度高、钻进深度深、所需能耗少)，已成为难进入地区、大位移井、超深井等钻柱设计的优选方案。本文从科普的角度介绍了钻柱与钻杆的区别、钻柱的使用极限长度、铝合金钻杆的技术优势及其现存的不足之处，以此提高对铝合金钻杆的认识，促进铝合金钻杆的研究和发展。 |

| Abstract:The development of earth sciences is more and more depending on the deep earth exploration data, the scientific ultra-deep drilling, known as “the telescope into the crust”, becomes an indispensable method for the research on deep geology. Compared with the steel drill pipe, the aluminum alloy drill pipe, with its unique superiorities (lighter weight, high specific strength, deep drilling depth and less energy consumption), has become the essential scheme for drill string design used in difficult to enter area, extended reach wells and scientific ultra-deep well and so on. From the perspective of popular science, this article describes the differences between drill string and drill pipe, the limit use length of drill string, the technical advantages of aluminum alloy drill pipe and the existing deficiencies, so as to improve our understanding of aluminum alloy drill pipe and promote the research and development of the aluminum alloy drill pipe. |
