含油气盆地的三维地质建模及可视化系统设计研究

3D Geological Modeling and Visualization System Design of Petroliferous Basin

以支持油气资源基础性地质调查、重点地区油气资源战略调查为目标,利用空间数据技术和基于Creatar Globe组件的地下空间三维可视化技术,将含油气盆地地质勘探调查成果统一在三维可视化信息平台中,面向地质调查专业人员和管理人员,提供集地表、地下空间信息于一体的大型综合性三维空间数据管理和服务。以羌塘盆地和半岛湖重点区块为例,通过多尺度三维地质信息综合展示技术,为研究人员提供一个直观的盆地勘探开发信息一体化查询、分析的可视化环境,提供不同视角、尺度范围、专题组合的三维地质视图显示,帮助提高各业务环节间的协同性,消除信息交流过程中产生的认识偏差,实现勘探科学部署、评价方案优化,从而提高勘查区块调查评价总体水平。

Taking supporting the oil and gas resources basic geological survey,key areas of oil and gas resources survey work as the goal,we used the spatial data technology and the underground space 3D visualization technology based on Creatar Globe component,and uni ed the results of geological exploration and investigation of petroliferous basins in 3D visualization information platform,which could provide a set of ground and underground space information in one of the large-scale comprehensive 3D spatial data management and service for geological survey professional and management personnel.In the Qiangtang Basin and Peninsula Lake key block,we used the multi-scale 3D geological information display technology to provide an intuitive information integrated query and visualization environment analysis of basin exploration and development for researchers,in order to provide di erent views of 3D geological perspective,scale,combination of thematic display,improve the coordination of the various business segments,eliminate the misunderstanding produced in the course of information communication,and achieve scientific exploration deployment and evaluation scheme optimization,so as to improve the overall level of investigation and evaluation of exploration blocks.
