摘要
激光拉曼光谱技术具有测试简便和精确的特点,通过对石油中沥青的拉曼光谱探针分析,可以研究石油沥青的物质成分特征以及形成演化过程。鄂尔多斯盆地石油沥青中广泛存在CH4等还原性气体,部分样品中同时还含有CO2等氧化性气体,且氧化性气体与还原性气体存在着此消彼长的反相关关系,这种关系及其互为消长的幅度也反映了盆地后期改造作用程度的高低。
The laser Raman technique has the merits of easy operation and more accuracy. Through the laser Raman microprobe analysis of bitumen in oil we can study the composition and evolution of bitumen in oil. Oil bitumen in the Ordos basin widely contains reducing gases such as CH4 and, in addition, some samples also contain oxidizing gas such as CO2. They have an antithetic relation. This relation and the antithetic range also reflect the degree of late-stage reworking of the basin.
