Abstract
The shale from the Carboniferous and Permian Taiyuan–Shanxi Formation in Kaiping syncline has good prospects for shale gas exploration and development. To understand the evolutionary characteristics of the sedimentary environment in this area and their relationships with organic matter enrichment. Shale samples from the Taiyuan-Shanxi in Well KP1 were selected as research objects, followed by organic geochemical research, elemental geochemical analysis, and numerical analysis. The results show that the sedimentary period of the Shanxi Formation was marked by a medium productivity level. The sedimentary water column was composed of brackish water and seawater deposits in an anoxic reduction environment. The Taiyuan Formation shale was characterized by a medium level of paleoproductivity. The sedimentary water column was composed of brackish water deposits in an anoxic reduction environment. According to the linear correlation analysis of paleoenvironmental conditions and TOC content. This study suggests that ancient water salinity is the main factor controlling the enrichment of organic matter in the sedimentary stage of the Taiyuan-Shanxi Formation.
