摘要: 通过1：25万三维地质调查，系统总结了基于MapGIS平台、DGSS数据库和CREATAR三维可视化技术，实现中比例尺三维地质建模及表达的技术方法.以地表地质调查成果为基础，综合地质、地球物理等多元信息，采用三维可视化技术，进行三维地质结构建模与推断，揭示地下一定深度的各种地质体和地质现象，表达各种地质体的三维空间展布及相互关系，为有效地进行地质研究和含油气盆地预测提供技术资料支撑.Abstract: This paper systematically summarizes the technical method of 3D geologic modeling with -medium scale (1:250 000) deep geological survey. Based on the service platform of MapGIS, database technology of DGSS and 3D visualization technology of CREATAR, the technical method of 3D geologic modeling with medium scale, and its visualization are realized. Adopting 3D visualization technology, on the basis of 2D geological survey result, synthesizing the multi-information about geology and geophysics, the 3D model of geologic structure is inferred and constructed, which can reveal the distribution and interrelation of various geologic bodies and geological phenomenon in certain depth underground. This method will offer technical support for the effective geological research and petroliferous basin forecasting.
