刚／柔性连接对导管架平台振动特性影响研究

摘要

海上油田二次开发时通常采取加密井网综合调整的措施，在工程上经常会在老平台旁建新的导管架平台。为满足设备和资源的共享，新老平台有刚、柔2种连接方式，即平台短距离直接连接或栈桥连接。分析了2种连接方式对新老平台整体振动特性的影响，得到不同情况下适宜的连接方式，并借助 SACS 软件进行工程实例验证。%Increasing the number of wellheads and comprehensive adjustment always use in rede-velopment of offshore oilfield.The new platform always was built beside the old jacket platform in redevelopment of offshore oilfield.There are two ways to connect the old and new platform to meet the sharing of equipment and resources.Researching was carried out for the vibration char-acteristics of jacket platforms influenced by rigid and flexible connection to prove the conclusions with SACS.
