摘要
张力腿平台在近年来深水油气田开发中得到广泛应用。顶张紧式立管是张力腿平台的关键部分之一,它连接水下井口与平台,十分重要。根据API RP 2RD规范,对张力腿平台的顶张紧式立管总体强度分析进行了探讨,并以中国南海340m(1116ft)水深某油田环境条件作为设计基础,采用单层管等效模型模拟多层管顶张紧式立管,利用Orcaflex软件对顶张紧式立管总体强度进行了分析,同时探讨了采用规则波或不规则波以及内孤立波对立管应力分析结果的影响,对今后顶张紧式立管的研究和设计具有一定的参考作用。
Tension Leg Platform （TLP） has been widely used in deepwater oil fieM development in recent years. Top Tensioned Riser MR） is one of the most important parts for TLP design, which connects subsea well and surface tree. TTR strength analysis method is discussed in this paper. An oil field in South China Sea with water depth 340m （1116ft） is taken as the design basis, TLP TTR global strength was analyzed by considering the influence of soliton for different load cases. The analyses carried out indicate that TTR have resultant stresses well below the allowable. This paper may have a certain reference value for future 7TR research and design.
