烃类物质的反射光谱特征研究及其油气勘探意义

通过新疆塔里木盆地西北缘柯坪隆起东部奥陶系石灰岩中晶洞油苗的反射光谱的浏试及其反射光谱特征的分析表明，烃类物质在1720nm附近具有吸收峰，在2310nm附近具有明显的双重吸收峰，Z150nm附近的吸收峰也可能由烃类物质所致;碳酸盐岩在2340nm附近具有CO^2-₃基团引起的强吸收谱带，随着其表面烃类物质的增加，其光谱反射率明显降低。

Renflectance Spectra Features of Hydrocabon and Its Significance on Petroleum Exploration

The analyses of reflectance spectra characters of hydrocarbon and limestone,whichcollected from the eastern Kalpin Uplift,Tarim Basin ,have shown that hydrocarbon hasobvious double absorption bands in 231 0nm, and weak absorption bands near1720nm and21 50nm,and limestone has absorption hand caused by CO near 2340nm. The researchresults have also indicated that spectra reflectance of limestone obviously reduced with theincreasing of content of hydrocarbon in limestone surface.
