特深钻探钻柱组合优化设计研究

摘要
钻杆柱作为地球深部探测中深地与深水钻探技术的核心与关键,单一规格钻柱许用深度有限,难以满足大陆万米特深孔科学钻探及大洋深水深孔钻探工程的设计要求。本文通过减轻下部钻柱重力及提高上部钻柱强度方案,对其组合设计开展优化研究。以拉伸条件下的强度计算为主,加之一定的设计安全系数和拉伸余量来满足动载荷以及其他复杂情况对钻柱强度的需求,并开发了钻柱组合设计与安全系数计算的软件,可实现不同孔深设计和钻杆结构要求下的钻柱组合设计与安全系数计算。
The drill string is the core and key technology in deep land and deep water drilling for deep earth exploration; however, with the limited allowable drilling depth, the drill string of a single specification is difficult to meet the design requirements of 10000 m extra deep continental scientific drilling and deep ocean drilling. In this paper, by reducing the weight of the lower portion of the drill string and improving the strength of the upper portion, the design of the drill string assembly is optimized. With the priority of tensile strength calculation, the demand on the drill string strength is satisfied in consideration of the safety factor and tensile allowance in case of dynamic loads and other complex situations, and the software for the drill string assembly design and safety coefficient calculation is developed, which can realize the drill string assembly design and safety coefficient calculation for different hole depths and drill rod structures.
