基于Inventor的水下生产虚拟仿真设计系统的设计与实现

经过近几十年的发展,我国海洋油气开发开始走向深海,为满足前期整体布局规划方案技术准备工作的需要,基于Inventor平台开发了水下生产虚拟仿真设计系统。该系统除在操作上使用方便、直观易懂外,还具以下功能:水下生产系统设备整体布局的快速设计;水下生产系统三维模型库的调用、自动添加、知识积累,模型浏览、预览,管线自动布设连接;对所创建的三维虚拟场景自动生成三维布局图或平面图;输出ROV工作的干涉报告;对关键部件、组件结构快速生成相应的有限元计算数据文件等。同时,为更好地进行快速设计,还以此平台为基础,对南海深水油气田荔湾3-1示范工程的水下生产设备创建了完整的参数化三维模型数据库。实际应用结果表明,该系统为我国的深水水下生产提供了一种快速、准确的方案比较工具,可对设备安装和水下生产关键技术进行预演,对深水油气勘探开发能起到一定的技术支撑作用。

Design and implementation of an Inventor based subsea production virtual simulation design system

After a few decades of development, China's offshore oil and gas exploitation starts to step into deep seas. In order to facilitate the technical preparations for overall early stage layout planning, a subsea production virtual simulation design system was developed based on the Inventor Platform. In addition to being intuitive and easy to use and understand, this system also has the following functions: a rapid design of overall layout of a subsea production system and equipments; the invocation, automatic adding, knowledge accumulation, model browsing, preview of a 3D model database of a subsea production system; automatic forming of a 3D layout or plan layout of a created 3D virtual scene; output of a ROV interference detection report; and a rapid generation of corresponding finite element calculated data files of key parts and component structures. Meanwhile, in order to achieve a better rapid design, a complete parameterized 3D model database was established based on this developed design platform for the subsea production equipment in the LW 3 1 Demonstration Project of Deepwater Oil & Gas Fields in South China Sea. The practical application shows that this proposed system is a tool for fast and accurate optimal selection of schemes for deepwater production in China. With this system, we can preview equipment installation and key subsea production technologies. This system is bound to promote the deepwater oil & gas development.
