【摘要】 三维数字盆地构造-地层格架的生成、显示、矢量剪切和空间查询是实现盆地分析信息化和可视化的关键技术。根据几何学和机械变形原理,在具有自主知识产权的GeoView三维可视化地学信息系统平台上,研发出了通过二维地震解释剖面图、构造平面图、沉积相平面图和钻井柱状图生成真三维盆地构造-地层格架的计算机模拟和可视化技术,以及建立三维数字盆地的空间信息系统技术。这些技术作为三维盆地模拟、油气系统模拟、断层封堵性分析、精细油藏描述、水平井可视化设计和剩余油分布分析等软件的开发基础,已经在一系列科技攻关项目和工程项目中得到成功的应用。更多还原

【Abstract】 Creating, displaying, vector cutting and spatial query of digital tectonic-stratigraphic framework are the key technology to realize visualization of the basin analysis. According to geometry and mechanical distortion principle, a computer simulation and visualization technique is developed, which uses 2D seismic interpretative profile, tectonic plan map, sedimentary facies map and well log sheet to generate 3D tectonic-stratigraphic framework of basin, and also to establish spatial information system of real 3D digital basin. The techniques are the basis of software development, such as 3D basin simulation, petroleum system simulation, fault sealability analysis, fine reservoir description, horizontal well visual design and analysis of remaining oil distribution etc.更多还原
