Affected by the multi-stage tectonic movements in Mesozoic and Cenozoic, the Paleozoic buried hill inner primary oil and gas reservoir with Carboniferous Permian as the source rock in Bohai Bay Basin has low understanding and difficult exploration. It is of great significance for the exploration of buried hill inner primary oil and gas reservoir to clarify the hydrocarbon generation evolution process of its source rock and its response relationship with the Mesozoic and Cenozoic tectonic evolution. Methods: Based on three-dimensional seismic data, measured vitrinite reflectance of typical wells, apatite fission track, fluid inclusion and other data, and further using technical means such as structural analysis, buried hill burial history analysis and basin hydrocarbon generation simulation, this paper discusses the Miocene tectonic movement and its control on the hydrocarbon generation evolution of Carboniferous Permian source rocks in Huanghua depression, Bohai Bay basin, The hydrocarbon generation period and favorable hydrocarbon generation range are defined. Results: The research shows that the Meso Cenozoic tectonic activity in Huanghua depression has experienced four evolution stages of "two stages of rifting and two stages of uplift", forming various types of burial history. The paleogeothermal change caused by tectonic movement is the fundamental reason for the differential hydrocarbon generation evolution of source rocks in the north and South regions. Among them, the rift formation promotes the rise of geothermal and is conducive to the hydrocarbon generation of organic matter, The compression transformation inhibited the rise of ground temperature and stopped the hydrocarbon generation of organic matter. Wumaying buried hill and Qibei buried hill have three hydrocarbon generation stages. The hydrocarbon generation stages are early Middle Triassic, early Cretaceous and Paleogene. Gangbei buried hill has two hydrocarbon generation stages. The hydrocarbon generation stages are early Middle Triassic and Paleogene. Conclusions: The hydrocarbon generation range in the early (i. e. early Middle Triassic) is limited, and the late (i. e. Paleogene) is the most favorable, Wumaying buried hill and Qibei buried hill are favorable areas for hydrocarbon generation.
