油气微渗漏遥感探测主要是建立在烃类微渗漏引起的地表地球化学异常的表征上,随着高光谱遥感技术的发展,高光谱遥感油气勘探近年来取得了很大的进展。以鄂尔多斯盆地为例,通过对Hyperion高光谱遥感数据处理与分析,提取了2个研究区油气蚀变的烃异常、黏土矿物异常、碳酸盐矿物异常和含铁矿物异常信息。结合地表波谱测试及化探数据,检验所提取遥感信息的可靠性,建立起了星—地信息之间的相关性。根据高光谱遥感综合异常,划分出了含油气远景区。高光谱遥感油气异常信息提取技术,为进一步的遥感定量研究和应用奠定了基础。
In recent years, hyperspectral remote sensing oil and gas exploration has made great progress with the development of hyperspectral remote sensing technology. Taking Ordos Basin as an example, hydrocarbon anomalies, clay mineral anomalies, carbonate mineral anomalies and iron-bearing mineral anomalies in two studied areas were extracted through Hyperion hyperspectral remote sensing data processing and analysis. Combined with the surface wave spectrum test and the geochemical data, the reliability of the extracted remote sensing information is tested and the correlation between the satellite and the earth information is established. According to the comprehensive hyperspectral remote sensing anomalies, the oil-gas prospect is divided. Hyperspectral remote sensing oil and gas anomaly information extraction technology, which laid the foundation for further remote sensing quantitative research and application.
