| description | Fanjingshan area in Northeast Guizhou is located at the northern margin of Xuefeng Uplift. The black organic rock series developed from Precambrian to Early Paleozoic, and the asphalt is widely displayed. The Neoproterozoic-Mesozoic period in this area experienced the Jinning period, Caledonian period and Indochina-Yanshan movement multi-stage tectonic deformation. Previous studies mostly focused on the response relationship between the structure and hydrocarbon accumulation in the latter two periods, while the matching relationship between the structure and hydrocarbon accumulation in the Jinning period has not been reported. In this paper, Re-Os isotopic study was carried out on bitumen in limestone dissolution cave of Baota Formation in Fanjingshan area. The isochronal age is (915±129)Ma. Combined with the regional geological analysis, it is concluded that there are primary oil reservoirs of Jinning period in Fanjingshan area, secondary oil reservoirs were formed in Caledonian period, whose distribution was controlled by paleouplift. In summary, this study enriches the oil and gas accumulation stages in the north margin of Xuefeng Uplift, and also promotes the study on the mechanism of secondary reservoir accumulation under complex tectonic deformation. It is of profound significance to the exploration of Neoproterozoic oil and gas in South China. |
