Abstract

Abstract

Abstract：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.
