摘要 介绍了激光雷达技术的工作原理以及数据的采集、处理和解释方法,展示了三维数字露头的构建过程。以塔里木盆地巴楚地区大班塔格剖面中奥陶统一间房组礁滩复合体为研究对象,在真实的三维数字露头地质构架下,以岩相与岩石物性关系为约束,构建了礁滩复合体三维地层结构模型、沉积相模型和储层模型,其结果真实地反映了地质情况。研究表明,基于激光雷达技术的三维数字露头改进了传统的露头建模研究方法,极大地提高了地质模型的精度,能为勘探开发提供有效指导。 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.
