摘　　要：三维综合地质建模技术可以对各地质实体与构造-地层系统的三维空间展布及相互关系进行可视化和立体化的展示。松辽盆地宝龙山铀矿床具有独特的成矿环境和成矿机制,文章在系统分析和处理松辽盆地宝龙山铀矿床及区域相关地质资料的基础上,利用综合地质与储层建模软件平台(GoCad)的半自动化流程建模法,分别构建了松辽盆地西南缘白兴吐构造剥蚀天窗-构造-地层模型和宝龙山典型铀矿床两个不同尺度的三维地质模型,最终构建了松辽盆地宝龙山铀矿床的三维地质实体模型,科学地展示了该铀矿床成矿环境和成矿地质条件,为砂岩型铀矿的成矿研究和资源量定量预测提供技术支撑。Three-dimensional integrated geological modeling technology can visualize and stereoscopically display the 3D spatial distribution and relationship between the geological entities and tectonic-stratigraphic systems.Baolongshan uranium deposit in Songliao Basin is unique in metallogenic environment and metallogenic mechanism.Based on the systematic analysis and processing of the Baolongshan uranium deposit and regional geological data in the Songliao Basin,this paper uses the semi-automatic process modeling method of the integrated geological and reservoir modeling software platform(GoCad)to construct two different scales of 3D geological models including the tectonic-stratigraphic model of Baixingtu structural denudation window and the 3D model of Baolongshan uranium deposit.Finally,the 3D geological entity model of Baolongshan uranium deposit was constructed,and the metallogenic environment and geological conditions of the uranium deposit were scientifically demonstrated.The work provided technical support for metallogenic research and resource quantitative prediction of sandstone-type uranium deposits.
