深水顶张式立管全耦合动力响应及参数敏感性分析
|
摘要
通过建立双套管与油管的全耦合运动控制方程,使用Newmark-β法,运用Matlab软件进行编程,对模型进行非线性时域动力耦合响应分析,分析在一定波浪环境,不同扶正器布置间距下,立管各层相同节点处耦合动力响应,研究各层管之间发生碰撞和摩擦的最大扶正器布置间距;分析相同扶正器布置间距下,不同顶张力系数对耦合动力响应的影响。结果表明:在波浪作用下,全耦合动力响应分析比等效管更能展现各层管的实际动力响应;扶正器布置间距与顶张力系数的取值不同,会影响各层立管的耦合响应与相对位移,取值不当时,立管会发生碰撞。
A nonlinear time domain dynamic coupling response analysis of the model is performed in certain wave environments and with different centralizer layout spacings,by establishing the fully coupled motion equations of the double casing and the tubing with the help of Matlab programming,using the Newmark-β method. Coupling dynamic response at the same node of the riser layer is performed to study the spacing of the maximum centralizer arrangement between collisions and frictions between layers of the riser; the influence of different top tension coefficients on the coupling dynamic response under the same arrangement spacing of the centralizers is also studied. It was found that the fully coupled dynamic response analysis can show the actual dynamic response of each layer of tubes,and more accurate than the equivalent tube; and the spacing of centralizer arrangement and the value of top tension coefficient are different and will affect the coupling response of each layer of risers. If the relative displacement is incorrect,risers will collide.
