摘要
采用航空短波红外分光谱遥感技术,在新疆准噶尔盆地和塔里木盆地某些油气区,进行直接寻找油气资源的试验研究后发现:油气区含油岩系、油气藏上方盖层土壤的光谱在2300和2350um波段具有双吸收特征;2270~2460um波段的反射率比相邻波段的反射率低15%~20%,这是遥感技术直接寻找油气资源的理论基础。该区油气藏上方普遍存在着烃类和放射性异常,碳酸盐异常仅在局部地方出现。图象处理提取出的油气遥感信息主要反映是烃类物质(以重烃为主)的2270~2460um波段的光谱信息。
In some oil-gas fields of the Junggar Basin and northern Tarim Basin, a study on direct search of oil and gas resources by using airborne short-wave infrared fine-split spectral remote sensing technique was made. The results led us to see that the spectral characteristics of oil-bearing rocks and overlying soils in the oil-gas fields show that the absorption spectra of hydrocarbons appear just at 2 310~2 350nm. Resufts of geochemical exploration indicate that hydrocarbons and radioactive anomalies usually exist in the soils above the oil-gas reservoirs, but carbonate anomalies occur only locally. The absorption spectral characteristics of hydrocarbons (dominantly heavy hydrocarbons ) at 2 270nm to 2 460nm can be developed from image processing of the remote sensing information on oils and gases.
