摘要:

在深水湿式开发应用中,海底管道中间或末端通过跨接管与水下井口或水下管汇连接.带有在线管汇的海底管道的温降曲线是不连续的,类似于把两条普通海管连在一起.有限元计算可以比较准确地预测出膨胀弯位移量,但计算复杂耗时较长.依托工程设计项目,使用解析方法,编程计算出带有在线管汇温降曲线不连续的海底管线的膨胀位移和轴向力.计算方法经过有限元计算的验证和第三方机构审查,适于工程应用.

关键词: 海底管道, 膨胀, 在线管汇, 有效轴向力

Abstract:

In wet development of deep water oil and gas, subsea pipeline is connected to subsea wells or manifold by jumpers at the middle or the ends. The temperature profile of pipeline with inline manifold is discontinuous, and like that of two pipelines connected together. Finite element analysis can accurately predict the expansion displacement, but the analysis is complex and time consuming. Based on an actual project, using analytical method, we develop an in-house work sheet to calculate the displacements of pipeline with inline manifold and discontinuous temperature profile. The calculation method has been verified by finite element analysis and reviewed by a third party. The method is applicable to engineering projects.

Key words: subsea pipeline, expansion, inline manifold, effective axial force
