| 摘 要： | 本文围绕烃类微渗漏造成地表土壤蚀变的褪红、粘土矿化和碳酸盐化等3项标志,在江汉油田进行了相关的地球化学信息和光谱信息研究。在研究土壤成分特征的基础上,提出了反映3项蚀变标志的成分因子;在研究土壤光谱特征的基础上,提出了与蚀变成分因子相关的TM波段比值因子;在成分因子及TM波段比值因子的统计分析基础上,探索从室内土壤光谱数据中提取和烃类微渗漏蚀变相关的信息,并为图像特征信息提取奠定了基础。

| Abstract: | This paper researches the geochemical and spectral information related to the "Red-fading", "Clay-mineralization" and "Carbonization" induced hydrocarbon micro-seepage in Jianghan Basin.Three content factors are extracted on the basis of researching the soil composition; three TM band reflectance ratio factors are extracted on the basis of researching the soil spectral characteristics, and the hydrocarbon microseepage alteration information are extracted successfully in laboratory from the soil spectral data. |
