摘　　要：本文以沱沱河地区为研究区,以天宫1号数据为信息源,在图像预处理的基础上,开展了天然气水合物烃类微渗漏蚀变信息提取工作,为该区天然气水合物勘探提供依据。研究结果显示:碳酸盐岩异常信息主要分布在本区中侏罗统布曲组(J_(2) b)地层中;黏土矿化异常信息主要分布本区中侏罗统夏里组(J_(2) x)地层中;二价铁离子异常信息主要分布中侏罗统夏里组(J_(2) x)地层中;烃类异常信息主要分布本区中侏罗统布曲组(J_(2) b)及中侏罗统夏里组(J_(2) x)地层中。结合岩性组合特征认为中侏罗统布曲组(J_(2) b)及中侏罗统夏里组(J_(2) x)地层是烃类物质存在的潜在区域。Taking Ulan Moron area as the research area,taking Tiangong No.1 data as the information source,and based on image preprocessing,this paper carried out the extraction of hydrocarbon micro leakage alteration information of natural gas hydrates,providing a basis for the exploration of natural gas hydrates in this area.The results show that the abnormal information of Carbonate rock is mainly distributed in the Middle Jurassic Buqu Formation(J_(2) b)in this area.The abnormal information of clay mineralization is mainly distributed in the Middle Jurassic Xiali Formation(J_(2) x)strata in this area.The abnormal information of divalent iron ions is mainly distributed in the Middle Jurassic Xiali Formation(J_(2) x)strata.The abnormal information of hydrocarbons is mainly distributed in the Middle Jurassic Buqu Formation(J_(2) b)and Middle Jurassic Xiali Formation(J_(2) x)strata in this area.Based on the lithological characteristics,it is believed that the Middle Jurassic Buqu Formation(J_(2) b)and Middle Jurassic Xiali Formation(J_(2) x)are potential areas for the presence of hydrocarbon substances.
