Extraction of hydrocarbon micro-seepage information based on TG-1 hyperspectral data
摘要
Abstract
The hydrocarbon microseepage detection method with remote sensing technology is a direct way for oil and gas investigation. According to several anomalous phenomena above oil and gas reservoirs, such as the enrichment of low-grade iron elements, the abundance of clay minerals and high carbonate content, this paper proposes an oil and gas alteration information extraction theory with hyperspectral method. Based on the theory,the authors analyzed the spectral response characteristics of various hydrocarbon alteration materials with hyperspectral data of the Tiangong-1(TG-1),highlighted targeted mineral feature information and at the same time suppressed the information of other ground objects, selected the high-absorption and high-reflection bands of the different interpretation signs,and then used the band ratio method to highlight and extract feature information. With the TG-1 hyperspectral data of Qingyang City,Gansu Province,the authors conducted oil and gas micro-seepage extraction and the results show that the distribution of the abnormal information of surface alteration is not only in good consistency with the local geological analysis results but also in good agreement with the actual oil and gas area data,thus verifying the feasibility of the method proposed in this paper and demonstrates the detection potential of TG-1 hyperspectral data.关键词
