摘要
Controlled by the multi-cycle superposition and reverse evolution of basin,the source rocks of Carboniferous-Permian coal-bearing strata has experienced secondary hydrocarbon generation in the eastern Liqing Depression,which shows a strong deviation in the space.The results of hydrocarbon generating history of these source rocks show that the Carboniferous-Permian source rocks entered the hydrocarbon generation window in the Early-Middle Triassic,then the hydrocarbon generation suspended in the whole region due to the Indosinian movement,after that the source rocks buried again in the Meso-Cenozoic and secondary hydrocarbon generation function occurred.
