摘要
本文介绍了贵州赤水天然气区某些地物的光谱特征。并结合地震、地质资料,以及岩石吸附烃分析和图像处理结果,对该地区的天然气遥感勘探进行了讨论。结果表明:烃类物质在近红外区(1.5～2.35μm)的光谱反射率比广泛出露在地表的砂岩、土壤和植物的反射率高;并且在2.31和2.35μm 波长附近具有典型的烃类吸收谱带。应用这些特征在 TM 图像资料处理中和航空短波红外分光扫描图像资料处理中,提取天然气遥感信息异常是非常有效的。
This paper introduced mainly the spectral features of some earth object in Chishui natu- ral gas region.On such a basis,with a combination of seismic and geological data and images processing techniques,the application of remote sensing on natural gas exploration were dis- cussed.The results show that some hydrocarbons display higher reflectances in a near in- frared range(1.5～2.35μm) than plants,soil and sand rocks outeroped on the earth surface, and it display feature of typical obsorption bands at 2. 31μm and 2.35μm.It is effective to ex- tract abnormelities from the remote sensing information of natural gas in the processing of TM image and images from air borne short wave infrared spectrum scanning by means of these characteristics.
