摘要
Based on the analysis of the vitrinite reflectance and apatite fission track inclusions system testing, the authors carried out the calculation of paleotemperature gradient and reconstruction of thermal history, and then identified the paleotemperature gradient of west slope and Bianminyang tectonic zone of Jinhu Depression. Through the analysis of the burial history-thermal history of typical single-well and the homogenization temperature of fluid inclusions, it can be identified that the accumulation period of Jinhu Depression was between 47～41.5 Ma. Then it could be judged that the Sanduo period（E2s）was the main hydrocarbon accumulation period of Jinhu Depression.
