鄂尔多斯盆地油气微渗漏高光谱信息提取研究

油气微渗漏遥感探测主要是建立在烃类微渗漏引起的地表地球化学异常的表征上，随着高光谱遥感技术的发展，高光谱遥感油气勘探近年来取得了很大的进展。以鄂尔多斯盆地为例，通过对Hyperion高光谱遥感数据处理与分析，提取了2个研究区油气蚀变的烃异常、黏土矿物异常、碳酸盐矿物异常和含铁矿物异常信息。结合地表波谱测试及化探数据，检验所提取遥感信息的可靠性，建立起了星-地信息之间的相关性。根据高光谱遥感综合异常，划分出了含油气远景区。高光谱遥感油气异常信息提取技术，为进一步的遥感定量研究和应用奠定了基础。

Study on the Hyperspectral Information Extraction of Oil and Gas Microseepage in the Ordos Basin

The mechanism of using oil and gas remote sensing to detect the hydrocarbon microseepage has geochemical abnormality.Hyperspectral remote sensing has been introduced to petroleum prospecting and a lot of progresses have been made.Taking Ordos Basin as an example,based on the Hyperion hyperspectral data,the abnormal information of oil alteration,clay minerals,carbonate minerals and iron minerals in two study areas were extracted.Combined with surface spectrum and geochemical data,the reliability of the extracted remote sensing information was tested,and a correlation between satellite and ground information is established.According to the hyperspectral anomaly,the oil and gas prospecting areas are described,and the foundation of quantitative research and application of remote sensing is established.
