| 摘 要： | 深井复合钻柱技术是解决特深科学钻探超长钻杆柱可靠性问题的重要途径,其与设备能力、材料性能、钻进条件及管柱力学等息息相关。本文系统总结了复合钻柱技术在我国深部钻探中的发展和应用情况,在复合钻柱强度理论的基础上,探讨了不同复合钻柱的组合方案及其极限下深。研究结果表明,若以?216 mm直径终孔,仅依靠钢质钻柱已无法满足特深钻探13000 m的下深要求,而采用V150钢级?127 mm钻杆配合?127 mm钛合金钻杆及S135钢级?127 mm钻杆配合?129 mm铝合金钻杆可分别满足最大13484 m和18783 m的下深要求,钻柱总重分别仅有360.5 t和324.3 t,均具备可靠的安全性保障。本文对特深科学钻探用复合钻柱的设计和选择具有参考意义。

| Abstract: | Deep-well combined drill string technology has become one of the most important scheme to solve the super-long drill string used for ultra-deep drilling project, which is related to equipment capacity, material property, drilling conditions and string mechanics. In this paper, the application and development of combined drill string technology in geological drilling are summarized systematically, the design scheme and its limitation length are discussed in detail on the basis of strength theory. The results show that the drilling mission with the depth of 13000m could not be finished by simply using pure steel combined drill string with the final borehole diameter being 216mm. By using drill string consisting of V150 steel drill pipe & titanium alloy drill pipe and S135 steel drill pipe & aluminum alloy drill pipe, the limitation depth and the weight of each combined drill string are respectively 13484m, 18783m and 360.5, 324.3t; in this way both of them own application reliability and advantage. These results have reference significance to the design and selection of deep-well combined drill string used for ultra-deep drilling project. |
