Abstract: With the fine and complicate target of geological study, the scale of the geological body characterization is smaller and more difficult. Reservoir distribution patterns and the existing prediction methods need to be improved. This paper reviews the traditional limitations of field geological investigation, and introduced technical features of unmanned aerial vehicle (UAV) and oblique photography, based on which it is proposed that the 3D digital outcrop characterization technique with UAV oblique photography. Subsequently, reservoir architecture patterns are analyzed by UAV collection model for instance. Research shows that seven aspects of the limitations of traditional geological investigation. However, UAV oblique photography has obvious technology advantages and innovative aspects. The collection and processing 3D digital model have anywhere location coordinate and image information, which fully meet the field outcrop architecture analysis. Example analysis found that collection and processing model architecture analysis of high resolution about 3~5 centimeter, architecture of sand body was researched more quantitatively and fine understanding. UAV oblique photography technology not only make digital outcrop to become a reality, but also to improve efficiency of geologists field outcrop investigation.
