Preliminary Source Rock Evaluation of Lower-Cretaceous Coal-Measures Strata in Hulin Basin in Northeastern China

Article Preview

Abstract:

According to the thermal decomposition achievement of coal shale and coal samples, which are gathered from the Lower-Cretaceous coal-measure strata of Hulin basin, the organic matter abundance, type and maturation have been analyzed with TOC, S1+ S2, Hydrogen Index, content of maceral, Tmax , Ro. The result indicates that the organic abundance of coal shale and coal in Qihulin formation is average ,kerogen type is type III and their thermal evolution is over mature . The organic abundance of coal shale in Yunshan formation is general to better while the coal’s organic abundance is from better to best, they are both type III kerogen, and their thermal evolution is mature. The above analysis indicates that the hydrocarbon generating potential is limited in the Lower-Cretaceous coal-measure strata of Hulin basin while coal-measure source rocks in the Yunshan formation have good hydrocarbon generating potential.
