摘　　要：abaqus是国际上最先进的大型通用有限元计算分析软件,具有强健的计算功能和模拟性能,拥有大量不同种类的单元模型、材料模型和分析过程。本文就是借助abaqus的强大功能,对深水无隔水管钻井中直接暴露在海水中的钻柱受力情况进行模拟。根据不同工况下的受力应力云图以及变形情况,确定其应力集中点。为深水钻井钻柱设计和校核提供可靠的理论依据和指导,具有较好的应用价值。ABAQUS is the most advanced large-scale general finite element analysis software,which has strong calculation function and simulation performance,and has a large number of different types of unit model,material model and analysis process.In this paper,the force simulation of drill string which is directly exposed in seawater during the deepwater drilling without drilling riser was carried out by the powerful function of ABAQUS.According to stress contour and deformation conditions under different conditions,the stress concentration point was determined,which can provide a reliable theoretical basis and guidance for design and check of the deepwater drilling.
