The sedimentary environment plays an important role in the enrichment of shale gas resources. In this paper, the characteristics of the marine-continental transitional sedimentary environments in the Bayanhot Basin are studied via laboratory analysis, scanning electron microscopy, and comparative analyses of field data. A differential analysis of the shale gas enrichment conditions was conducted by comparing the shale organic geochemical characteristics and performing a petrophysical analysis of the southern and northern sedimentary environments in the Bayanhot Basin. The findings showed that (1) the hydrocarbon-generating potential of the shale in the northern delta sedimentary environment is better than that of the shale in the southern combined sedimentary system based on the total organic carbon content and organic matter type and (2) the shale in the southern Bayanhot Basin, which has better shale petrophysical microcharacteristics, presents superior gas accumulation and fracturing operation characteristics compared to the shale in the northern part.
