Abstract:

In order to improve the shortcomings of the traditional method of outcrop research and cognize geological information more objectively and comprehensively from outcrop, the laser radar technique was applied to the study of outcrop stratigraphic mapping. With the use of computer visualization, this paper constructed digital outcrop of Yangjiagou section of the Upper Triassic Yanchang Formation, Ordos Basin. Geological information extraction and analysis were carried out based on digital outcrop, such as the sequence stratigraphy, sedimentary cycle and sand body distribution of Chang 3 oil reservoir set of Yanchang Formation. Through establishing typical sequence boundary identification marks and combining with the theory of sequence stratigraphy, sequence boundary identifying and tracking on digital outcrop were conducted and a fourth-order sequence boundary was identified. A positive cycle and a reverse cycle were respectively developed above and below the boundary, and the location of the thickest sand body is corresponding to the fourth-order sequence boundary. Through establishing sedimentary cycle identification marks, tracing and contrasting sedimentary cycle interface on digital outcrop, three asymmetric short-term cycles were identified. These three short-term cycles can compose a fourth-order base level rising half cycle. It is a set of the overall upward trend of the fourth-order parasequence-set, with the trend of decreasing thickness upward of sand body. Through the establishment of sand body interpretation marks, typical channel sand body were respectively identified at the bottom of the fourth-order base level cycle and the top of the profile. And then, fine description and comparison of the internal layer of single sand body was made according to the outcrop anatomy. Comparison results show that the main lithology of the profile is fine sand and coarse silt, locally clipping dark mudstone or shale.
