| 摘 要： | 根据冀中坳陷大量钻井岩性剖面、地震测线和实验室分析等资料，运用沉积学、层序地层学和石油地质学等多学科理论为指导，深入研究冀中坳陷下第三系区域地质特征、层序地层特征、沉积环境变迁、沉积相带展布和油气分布状况。把冀中坳陷下第三系划分为断陷分割充填期、断陷扩张深陷期、断陷萎缩期、断坳扩展期和断坳抬升消亡期五个演化阶段。最终把区内12个凹陷划分为继承型、早盛型、过渡型、偏移型和沉降型五种类型湖盆，并对它们进行了含油气评价；指出廊固和坝县凹陷具有良好的油气勘探前景，是今后油气勘探的主攻方向；饶阳凹陷东部、晋县和束鹿凹陷，要立足小断块，不断发现小油藏，保证冀中油气长期稳产。

| Abstract: | Based on intensive investigation of the borehole core lithology, seismic survey lines and laboratory experimental data, and with the instruction of the interdisciplinary theories of sedimentology, sequence stratigraphy and petroleum geology, the regional geology, sequence stratigraphy, evolution of sedimentary environments, distribution of sedimentary facies zones and oil and gas distribution of the Palaeogene in the Central Hebei Depression have been studied. The study shows that the Central Hebei Depression has undergone 5 evolution stages, which refers successively to the rift segmentation filling stage, the rift spreading and deep subsiding stage, the rift withering stage, the rift depression expanding stage, and the rift depression lifting and vanishing stage. A total of 12 sags in the Jizhong Depression have been classified into 5 types of lacustrine basins, that is inheriting type, early prevailing type, transitional type, migratory type and subsiding type. Oil and gas bearing evaluation of these different types of lacustrine basins indicates that the Langgu and Baxian sags, which have better prospects of oil and gas exploration, will be the main direction of oil and gas exploration. On the contrary, the Jinxian, Shulu, and eastern Raoyang sags should base upon their small faulted blocks to continuously find smaller pools to ensure the long term steady output of oil and gas in the Central Hebei Oilfiled. |
