摘　　要：根据流体包裹体均一温度、盐度、拉曼光谱和储集层自生伊利石K Ar同位素测年的研究结果 ,冀中坳陷文安斜坡上古生界煤成烃油气藏的形成有两期 ,第一期发生在中生代末 ,但成藏后被其后的燕山运动破坏 ;第二期在古近纪 ,是本区油气藏形成的主要时期。冀中坳陷上古生界原生油气藏勘探应以二次生烃区周围喜马拉雅期形成的圈闭为目标。图 3表 1参The analyses of homogenized temperature of fluid inclusion, Roman, salts and the K-Ar age dating of authigenic illite within the reservoirs suggest two stages of the Paleozoic coal-derived reservoir-forming in the Wen'an slop of the Jizhong Depression, Bohai Gulf Basin, including at the end of the Mesozoic era and in the Paleogene, respectively, in which the first one had been destroyed by the Yanshan movement and the another one was formed in Paleogene, a major stage of reservoir-forming in the studied area. The plays in the Jizhong Depression should be focused on the traps formed during the Himalayan episode, and where would be the secondary hydrocarbon generation areas.
