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 world’s most advanced large-scale universal finite element analysis software, with robust computing capabilities and simulation capabilities, with a large number of different types of cell models, material models and analysis process. This article is based on the power of abaqus to simulate the forces on the drill string exposed directly to seawater in deepwater non-riser wells. According to different conditions of the stress stress cloud and deformation, to determine the stress concentration point. It provides a reliable theoretical basis and guidance for the design and verification of deepwater drilling string and has good application value.
