【摘要】：近些年来随着计算机技术的兴盛发展,将传统工业生产与计算机技术相结合的领域越来越受到关注和重视。尤其是在石油工业方面,通过计算机模拟油藏地质建模来指导油气田开发已经成为一种趋势。本论文中采用基于Open GL的面向对象三维图形软件开发包Open Inventor(统一简称为OIV)和其扩展模块Mesh Viz、Volume Viz,以及用户界面开发工具Qt,通过构建油藏地质模型来设计、并实现一个可视化软件系统。使用该系统可以完成多种地质图件的绘制,包括地层厚度图、物性参数模拟结果图、三维立体图、连井剖面图等。利用这个系统,指导石油地质人员准确的理解各种复杂的油藏地质现象和油藏地质构造,使得可以加快油气勘探开发的进度,并且为之提供决策依据。本文首先分析并归纳了油藏地质建模和计算机可视化技术的基本理论。将油藏地质模型可视化分为油藏地质建模和可视化两个过程。在油藏地质建模方面,阐述了油藏地质模型的基本概念、分类、建模方法和具体流程,研究了油藏地质模型的完整建模过程。在可视化方面,研究了可视化的基本原理以及将可视化技术运用到油藏地质模型中的具体流程。其次,研究OIV和Qt可视化油藏地质模型的方法和关键技术。详细描述了OIV及Qt的产生发展、功能特点和主要结构,并且分析了OIV的扩展模块。为后续的开发奠定有力的技术基础。最后,通过使用OIV图形开发软件、Qt用户界面开发框架,设计并实现了油藏地质建模可视化系统。利用OIV的基础模块构建场景,应用其Mesh Viz及Volunme Viz模块绘制地层等厚、沉积相模型、三维立体、连井剖面图等地质图件。通过使用油田的实际数据进行测试,系统可以绘制出多种地质图件,真实再现了油藏地质的形态特征和空间分布。结果表明,该系统具有交互功能,用户可以在显示的图件中进行一系列操作,拥有强大的数据处理能力、可靠性、实时性的特点。
[Abstract]:In recent years, with the development of computer technology, more and more attention has been paid to the field of combining traditional industrial production with computer technology. Especially in petroleum industry, it has become a trend to use computer to simulate reservoir geological modeling to guide oil and gas field development. In this paper, Open inventor, an object-oriented 3D graphics software development kit based on Open GL, and its extension module, Mesh Vizn Volume Vizor, and the user interface development tool QT, are used to design the reservoir geological model. And realize a visual software system. The system can be used to draw various geological maps, including formation thickness map, physical parameters simulation result map, three-dimensional stereogram, even well profile map and so on. By using this system, the petroleum geological personnel can be guided to understand various complex reservoir geological phenomena and reservoir geological structures accurately, so that the progress of oil and gas exploration and development can be accelerated, and the decision basis can be provided for them. In this paper, the basic theories of reservoir geological modeling and computer visualization are analyzed and summarized. The visualization of reservoir geological model is divided into two processes: reservoir geological modeling and visualization. In the aspect of reservoir geological modeling, the basic concept, classification, modeling method and concrete flow of reservoir geological model are expounded, and the complete modeling process of reservoir geological model is studied. In the aspect of visualization, the basic principle of visualization and the process of applying visualization technology to reservoir geological model are studied. Secondly, the methods and key technologies of OIV and QT visualization reservoir geological model are studied. The generation, development, function and main structure of OIV and QT are described in detail, and the extended module of OIV is analyzed. Lay a strong technical foundation for further development. Finally, a visualization system for reservoir geological modeling is designed and implemented by using OIV graphical development software and QT user interface development framework. The basic module of OIV is used to construct the scene, and the Mesh Viz and Volunme Viz modules are used to draw geological maps such as formation equal thickness, sedimentary facies model, 3D stereo and even well profile. By using the actual data of the oil field, the system can draw a variety of geological maps and reproduce the morphological characteristics and spatial distribution of the reservoir geology. The results show that the system has interactive function, users can perform a series of operations in the displayed drawings, and has the characteristics of powerful data processing ability, reliability and real-time.
