高光谱在油气勘探中的国内外研究现状

随着科技的发展,遥感在油气勘探的作用越来越大。高光谱作为遥感发展的最新手段,自然也受到油气勘探领域的重视。高光谱遥感具有快速,经济,精确的特点。通过高光谱探测油气渗漏和其引起的地表矿物蚀变、植被变化的范围,进而确定油气勘探的区域。高光谱在油气勘探领域的应用实例相对较少,在数据和处理方法上还存在很多不足;比如现有的卫星高光谱数据覆盖范围有限(空间分辨率也较低),数据处理方法大多是原有的多光谱数据处理方法,针对高光谱数据在油气勘探中的处理方法不多。随着高光谱遥感仪器精度的提高和数据处理方法的改进,高光谱遥感必将为油气勘探提供新的机遇。

The hyperspectral research status at home and abroad in the oil exploration

As the development of the technology, the RS play a more important role in the oil exploration. The hyper spectral was the new technology of RS, so it got more attention in the oil exploration. The hyper spectral remote sensing characterized with high-speed, cheap, accurateness. There were little oil exploration examples which use hyperspectral. And there were lot of deficiencies in the data and process method. For example, the cover area of the hyper spectral satellite is limited (and the spatial resolution is small), a lot of the process methods in the hyper spectral which was use for multi-spectral processes, there were little process methods for the hyper spectral in the oil exploration. As the development of the hyper spectral instruments and its process methods, the hyper spectral will provide new chance for the oil exploration.
