3D Geological Modeling and Its Application under Complex Geological Conditions

3D modeling technique has become a favorable tool for people to observe and analyze the world, and has been used widely in various trades. Geological body enrich mineral resources, and the spatial shape and petrophysical distributions of geological body are controlled by geological conditions. So 3D geological modeling under the control of complex geological conditions becomes the research emphasis. This article analyzes the uncertainty, complexity and diversity of geological body, and lists complex geological conditions controlling spatial shape and petrophysical distributions of geological body. And then 3D geological modeling method under the control of complex geological conditions is proposed, and corresponding modeling workflow is set up. Finally, taking 3D geological modeling of petroleum exploration and development for example, 3D geological model of Yulou oil formation, Jin-16 block, Liaohe oil-field, is built and some applications like 3D visualization of geological body are realized.
