摘　　要：深海油气田开发中,干式采油树比湿式采油树具有更多优势。在半潜平台下部安装垂荡板可减小运动响应,从而使其能够采用干式采油树。本文基于多浮体三维势流理论,采用数值模拟和模型试验相结合的方法,对垂荡板和干树半潜平台组成的复杂垂向耦合多体系统的运动性能展开研究。数值计算结果与试验结果吻合良好,两结果均证明该新型平台拥有良好的运动性能。同时,对不同伸缩立柱长度和不同下浮箱重量展开逐步探索,得到其对垂向耦合多体低运动半潜平台运动性能的影响规律。本文的研究结果可为新型干树半潜平台的优化和使用提供参考。In the development of deep-sea oil and gas fields,a dry tree system has more advantages than a wet tree system.Installation of a heave plate at the lower part of a semi-submersible platform can reduce the motion responses,which enables the use of a dry tree system.In order to investigate the motion performance of a complex vertically-coupled multi-body system composed of a heave plate and a dry tree semi-submers⁃ible platform,a combination of numerical simulation and model test was used in this paper to examine the new platform based on 3D multi-body potential flow theory.The numerical calculation results are in good agreement with the experimental results,and both results prove that the new platform has excellent motion re⁃sponses.Meanwhile,different telescopic column lengths and lower pontoon weights were explored systemati⁃cally,and their influence on the motion performance of the coupled multi-body system was obtained.The re⁃search results of this paper can serve as a reference for the optimization and use of new dry tree semi-sub⁃mersible platforms.
