两腿三桩简易平台设计摘 要. 随着社会经济的发展，人们对能源的需求不断扩大，海洋石油资源逐步成为新的能源增长点。因此作为海上石油开采的立足点一海洋采油平台的作用越来越重要。我国己经探明的边际油田储量为13亿吨，无论是对国家、石油开采部门，还是对平台结构设计研究者，开发和建造一种轻型、安全、可靠的海洋平台对开采边际油田是至关重要的。本文针对浅海边际油田的特点，从投入成本和产出效益角度考虑，设计了一种导管架式两腿三桩简易平台。运用ANSYS有限元软件，建立平台有限元模型。在考虑了海风、海流、海冰和波浪等环境荷载的基础上，对其结构进行了静力分析和动力分析。分析结果表明，该平台在各种载荷的作用下，完全满足强度和稳定性要求，具有较大的安全储备。 关键词 简易平台 边际油田 导管架 ANSYSThe Design Of Two-Legs Jacket PlatformAbstractWith the rapid development of economy in China, the need of energy source is increasing continually. The exploitation of offshore oil field is the key to make up the lack of continental oil field. The platform becomes important increasingly.The proved reserve of marginal oil field exceeds 1.3 billion tons in offshore. For our country , the exploiting department or designer, it is crucial to invent and manufacture a kind of light, safe and reliable platform to exploit the marginal oil field. Aimed at the characteristic of marginal oil field,and considered the cost and benefit, this paper designs simple jacket platform with three pipes,one of which is under water. Firstly, founded FEM models by means of the software ANSYS. Considered the load of wind,ice,wave and ocean current, static and dynamic analysis on the single-leg jacket platform was employed.The results shows that the jacket platform satisfies the request of strength and stabili
