| 摘 要： | 应用陆地卫星 TM 资料对南盘江地区进行了烃类微渗漏蚀变信息检测研究。岩石土壤地球化学特征分析表明,该区不同程度地存在着“褪红”、“粘土矿化”、“碳酸盐矿化”等烃类蚀变异常现象。选择 FeO/Fe_2O_3作为褪红的成分因子;(K_2O+Na_2O+Al_2O_3)、(K_2O+Na_2O)/Al_2O_3、(K_2O+Na_2O+Al_2O_3)/S∶O_2和 K_2O/Na_2O 等作为粘土矿化的成分因子;CaO+MgO 和 CaO/MgO 作为碳酸盐矿化的成分因子。利用 TM1/TM3、TM1/TM4识别褪红蚀变信息,TM5/TM7、TM5/TM4用干识别粘土矿化和碳酸盐矿化蚀变信息。建立了地球化学—光谱—遥感图像三位一体的遥感找油气模式,根据油气遥感色调异常对南盘江地区进行了评价和分类。 |

| Abstract: | Alteration information detection of hydrocarbon microleak in Nanpanjiang region has been studied by TM data got from land satellite.Rock and soil geochemical characteristics analysis suggests that hydrocarbon alteration phenomena,such as red decolorization,clay mineralization,carbonate mineralization, atc.,to different extent occur in the region.FeO/Fe_2O_3 is chosen as a compositional factor of red decolorization;(K_2O+ Na_2O+Al_2O_3),(K_2O+Na_2O)/Al_2O_3,(K_2O+Na_2O+Al_2O_3)/ SiO_2 and K_2O/Na_2O are chosen as clay mineralization ones; CaO+MgO and CaO/MgO as carbonate mineralization ones. The red-decolorization alteration information is distinguished by TM1/TM3 and TMI/TM4,and cqslay and carbonate mineralization by TM5/TM7 and TM5/TM4.The geochemical- spectral-remote sensing exploring oil-gas model is then set up based on oil-gas remote sensing color anomaly with which Nanpanjiang region has been assessed and classified. |
