Abstract
This paper uses high-precision remote sensing and laser scanning to study petroleum geological analysis methods. The research area is Karamay Formation in Junggar Basin, China. Firstly, the outcrop lithologies are identified according to our clastic rock lithology identification pattern based on laser intensity, and the regional lithologies are identified based on high-precision remote sensing images. Furthermore, we analyze the horizontal and vertical distribution characteristics of the sandbodies. At last, we analyze the area sandbody connectivity and sandbody structure characteristics. These data can provide basic information for the analysis of underground reservoirs in Karamay Formation.
Highlights
Digital outcrop is an effective method to realize the research of underground reservoir analogues
Zeng et al.[4,5] studied the extraction of geological information from a digital outcrop based on lidar, and Zhu et al.[6] developed sedimentary reservoirs based on digital outcrop technology, Zheng et al.[7] studied the application of digital outcrop in reservoir geological modeling
Sheng et al.[8] realized the estimation method of sandstone outcrop porosity based on hyperspectral; some abroad scholars have used laser intensity to explore lithology identification[9]
Summary
Digital outcrop is an effective method to realize the research of underground reservoir analogues. The digital outcrop based on remote sensing and ground laser scanning can study the outcrop reservoir structure intuitively, quantitatively and precisely. There are literatures that are currently studying the extraction of effective geological information based on lidar data and digital models[1,2,3]. High-precision remote sensing and lidar technology are used to establish the digital outcrop model of the Karamay Formation in Shendigou area of the Junggar Basin. Combined with the ground geological survey, the lithology identification and quantitative characterization are carried out, and the structural characteristics of the surface sandbodies of the Karamay Formation are analyzed to provide basic data for reservoir analysis
