【摘要】 地震勘探解释成果图是石油勘探开发行业最常用的一种图件。伴随着计算机技术和信息技术的飞速发展,传统2D方式已经不能满足各行业多方位、多层次对地层构造查看分析的需求。通过对地震勘探解释成果图所展示的复杂地层进行建模,并对其进行三维可视化显示和查询,就能有效地为油气勘探开发提供决策依据。为此,本文对复杂地层一体化数据模型构建及其三维可视化进行了详细的研究,并开发了基于此项研究的海洋地质三维可视化系统(简称MG3D)。1.介绍了复杂三维地层建模方法。在研究地震勘探解释成果图数据需求分析的基础上,研究了地层、断层、井的建模方法,并根据可视化展示的需求,制订了一体化数据模型结构,实现了建模与可视化的数据接口。2.总结了Open Inventor三维引擎特征及应用的关键技术。文章介绍了Open Inventor发展、主要结构及其特点,并且介绍了所应用的三维可视化关键技术。3.研究了基于复杂断层建模与三维可视化展示的MG3D系统设计方法。文章结合海洋地质可视化软件开发项目的实际应用需求,提出了系统总体构架设计方案,并对其各功能模块作了介绍,在此基础上,详细设计了系统的文件结构、数据处理流程、OIV场景图和程序结构。4.开发了海洋三维地质可视化系统。基于.NET平台采用C#语言开发海洋三维地质可视化系统,该系统包含了模型构建模块、模型编辑模块和可视化展示模块。并实现了文件管理、对象管理、视图控制、属性管理以及模型管理的功能。通过对实际地震勘探解释成果资料的应用,表明了海洋三维地质可视化系统能很好实现复杂三维地层融合建模,并能准确的对一体化数据模型进行三维可视化展示,具备一定的独立性和较好的通用性,可以广泛应用于石油地质领域。更多还原

【Abstract】 Seismic interpretation map is commonly used in oil industry exploration and development. With the rapid development of computer technology and information technology, the traditional 2D methods can not meet the demand of multi-directional, multi-level view of the stratigraphic structure. Modeling complex stratum showed on the seismic exploration map, displaying and quering it in three-dimension, which can effectively provide decision support for the oil and gas exploration. Therefore, this paper made a detailed study on the complex stratum integrated data model and the three-dimensional visualization, furthermore, we developed marine geology three-dimensional visualization system based on this study (Short for MG3D).1. Introduced the modeling method of the complex stratum. Based on the demand analysis of seismic exploration data, this article made a study of stratum\fault and well modeling, drew up integrated data model structure based on the demand of visual display, and achieved the data interface of modeling and visualization.2. Summed up the characteristics of open inventor 3D engine and the key technologies of application. This paper introduced the development, the main structure and characteristics of Open Inventor, and the key technologies of three-dimensional visualization, which are used in Open Inventor.3. Researched the designing method of MG3D system based on complex fault modeling and 3D visualization display. Combing with the practical application demand of marine geology visualization software , this article proposed overall system architecture design, and introduced its various functional modules, Meanwhile, the system detail file structure, data processing, OIV scene graph, and program structure are designed.4. Developed marine geology three-dimensional visualization system. Based on the NET platform, Marine geology three-dimensional visualization system is developed using C# development language. This system includes model building module, model editing module and visual display module, which realize the document management, object management, view control, property management and model management functions.Through the actual application of seismic interpretation data, it shows the marine geology three-dimensional visualization system well support complex three-dimensional stratum modeling, and display the three-dimensional visualization of integrated data model accurately, which indicate the system has a certain degree of independence and a better general performance, therefore, it can be widely used in the area of petroleum geology.更多还原
