【摘要】 随着卫星和传感器技术的发展,遥感技术已广泛应用于油气资源调查与勘探,且发挥着越来越重要的作用。通过阐述油气烃类微渗漏模型,认为油气烃类微渗漏可以导致海表烃类气体、油膜异常及喜烃类生物聚集。并以南海北部边缘盆地为例,阐明了海洋油气遥感探测的3种方法:①利用红外波段反演海表温度异常。②利用合成孔径雷达检测海表油膜异常。③喜烃类生物的增加导致海表光谱异常,以及利用水色遥感技术检测海表微生物含量异常。最后,对海洋油气遥感的未来发展趋势进行了展望。更多还原

【Abstract】 Along with the development of satellites and sensors technology,remote sensing technology has been applied to survey and detection of gas and oil resource,acting a more and more important role.This article introduces the hydrocarbon microseepage model of gas and oil reservoirs,figuring out that hydrocarbon seeped from reservoirs can lead to abnormity of hydrocarbon concentration,oil slicks and microorganism which lives for hydrocarbon.Taking north part of South China Sea as example,we introduce three remote sensing methods of oil and gas offshore:① Calculating SST by infrared band.② Detecting oil slicks by SAR(Synthetic Aperture Radar).③ Detecting concentration of microorganism on sea surface by ocean color remote sensing,due to abnormity of sea surface spectrum led by increasing of microorganism which lives for hydrocarbon.Finally,this article brings forward some prospects for the remote sensing development of gas and oil offshore.更多还原
