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 article describes the extension of NOAA / AVHRR image data for remote sensing of oil and gas resources in Jianghan Basin. The AVHRR band 5 (red), band 2 (green), band 1 (blue) false color composite image can clearly understand the macro-structural contour of the Jianghan basin periphery; take AVHRR band 1, band 2, band 4 as non- Supervised and processed 32 sub-categories to obtain a relatively stable lacustrine sedimentary range (ie, the main oil-producing rock area) in this basin. In AVHRR, Band 1, Band 2 and Band 5 were classified as non-supervised and classified into 32 categories in combination with TM According to the thermal thermal inertia mapping, it is found that the thermal inertia of the main oil and gas sector in this basin lies between the highest and lowest visual thermal inertia distribution in this basin.
