摘要
本文结合南海"荔湾3-1"深水油气田的环境特征,深入研究SCR立管顶部柔性节点的内部结构,详细分析了波纹管、弹性体等主要部件及其相互作用。以0.3048m立管为例,设计出符合荔湾1500m水深的耐高温高压柔性节点。用ABAQUS有限元分析软件对其进行了非线性分析及强度校核,并对比分析了传统柔性节点,得出耐高温高压柔性节点更符合深水等复杂环境的要求。
In this paper, flexible joints applicable for ＂Liwan3-1＂ deepwater gas field in South China Sea are based on study on the internal structure, the major components and their interaction are analyzed in detail, such as bellows and elastomer. Take 0. 3048 m of SCR for example, suitable flexible joints for 1 500 m deep water in ＂Liwan3-1＂ is designed. Then, nonlinear analysis is made for High Temperature High Pressure Flex Joint（HTHP-FJ） using ABAQUS, and comparative analysis with Traditional Flex Joint（T-FJ）. The results show that HTHP-FJ is better to meet the requirements.
