摘要
本文介绍了将NOAA/AVHRR图像数据扩展用于江汉盆地油气资源遥感勘查。将AVHRR的波段5(红)、波段2(绿)、波段1(蓝)假彩色合成的图像能清楚地了解江汉盆地周缘的宏观构造轮廓;取AVHRR的波段1,波段2,波段4作非监督处理分32类,得到该盆地较稳定的湖相沉积范围(即主要的生油岩区);取AVHRR的波段1,波段2和波段5作非监督处理分出了32类,并结合TM资料发现了该盆地3条基底断裂线性构造;用视热惯量制图,了解到该盆地主要的油气区段的视热惯量介于该盆地视热惯量分布的最高与最低之间。
This paper introduces the application of NOAA/AVHRR image data on oil & gas exploration in Jianghan Basin. The color composite image of band 5(R), band 2(G), and band 1(B) indicates the macrotectonics of the Basin clearly. From the unsupervising processing image of band 1, band 2 and band 4(32 types) the source rocks areas of the basin are defined. In the unsupervising processing image of band 1, band 2 and band 5(32 types), three fundamental structures are interpreted, which control the oil & gas distribution. The mappimg of the Apparent Thermal Inertia (ATI) indicates that the oil & gas riching areas are mainly distributed between the biggest and smallest ATI areas.
