| Abstract: |
| The working principle of LIDAR and the methods of LIDAR data acquisition, processing and interpretation are introduced and the establishment process of a digital outcrop is shown. The Middle Ordovician Yijianfang reef-beach facies carbonate body at Dabantage outcrop in Bachu Uplift is selected to set up a 3D digital outcrop. According to the real geological framework of 3D digital outcrop, and constrained by the lithology and physical property of the body, the three-dimensional stratum structure model, sedimentary facies model and reservoir model are set up. All the models match well with the actual geological conditions. It is shown that the technology of LIDAR-based 3D digital outcrop can improve the investigation method of conventional outcrop modeling and increase the accuracy of geologic models. |
