【摘要】 本文基于塔里木盆地塔中地区志留系—泥盆系的岩相古地理研究,绘制了研究区的构造背景图、沉积相分布图和储层评价图等基础地质图件。利用地理信息技术和虚拟现实技术建立了能够管理研究区复杂生物遗迹信息和勘探图件的地质信息系统;采用面向对象的方法进行了系统的分析、设计和实现;开发成果软件《生物遗迹地质信息系统》在空间数据的管理、查询和分析等方面有别于传统的数据库管理系统。系统分十二个功能模块,实现了生物遗迹和岩石物性信息的录入、编辑、修改、查询等数据库管理功能和遗迹化石的分类统计、单井柱状图和连井对比图的自动绘制、沉积相和储层评价的分析结果查询、地层取芯模拟、生物遗迹化石单体形态和形成过程的模拟以及成果图件的输出等高级功能。在应用研究方面取得了以下三方面的进展:①利用系统的自动成图功能绘制了研究区的单井柱状图和连井对比图;②在绘制的柱状图基础上,对研究区地层进行三维建模,综合遗迹化石、岩性等物化资料,模拟了三维地层的取芯情况;③结合研究区的沉积、构造信息建立了研究区的三维沉积体系模式图。更多还原

【Abstract】 Based on Silurian-Devonian lithofacies palaeogeography research, the tectonic background maps, sedimentary face maps, reservoir evaluation maps and other basic geological maps of the center of Tarim basin are drawn in this paper. The Geological Information System was built by applying GIS and virtual reality technique, which can be used to manage the complex exploration geological information and exploration-produced graphics. analyse, design and development of the system were performed by adopting the Object Oriented Method. The developed software (Ichnological and Geological information system) is different from a traditional Database Management System in query, management and analyse essentially.The system includes twelve functional module, which accomplishes biology information synthetically managing, such as information inputting, editing, modifying, query and so on,and other advanced function, such as trace fossils calculating, drawing automatically drill columns or correlograms, sedimentary environment analyzing query, reservoir evaluation query, lithology core simulation, shape and forming process simulation of single trace fossil etc. Three aspect of achievement was acquired in application research as follow:①Exploration drill columns and correlograms of research area were drawn by applying the drawing map automatically functions.②Based on the drawn histograms, the lithology core of research area was simulated by synthesizing trace fossils information, lithology information and physical or chemical materials.③the 3D sedimentary system patterns of research area were drawn by integrating sedimentary information with tectonic information.更多还原
