摘　　要：东营凹陷和高邮凹陷分属渤海湾盆地与苏北盆地,是中国东部中、新生代陆相断陷盆地中的典型凹陷,无论从构造角度、沉积特征还是从石油地质条件,都具有颇为重要的代表意义。因此,本文立足沉积学理论的基本观点,综合利用前人研究成果,以构造区带为单元,以构造与沉积演化为主线,以沉积相时空展布为内容,以沉积充填特征为核心,采用逐一对比的方法,总结出东营凹陷与高邮凹陷古近系构造格局与沉积格局“整体上类似、局部上差异”的根本性原因及其控制因素。Dongying depression and Gaoyou depression, belonging to Bohaiwan basin and Subei basin respectively, are the typical Meso-Cenozoic depressions in continental faulted basins in the east China. And, they are significant whether from tectonic view or from depositional characteristics or from conditions of petrolic geology. Therefore, this paper based on the points of sedimentary theory, makes use of results of predecessors. Using the tectonic districts as unit, taking the evolvement of tectonic and deposition as main clue, utilizing distribution of sedimentary facies in temporal and spatial position as content, considering the characteristic of depositional filling as key, through the methods of contrast, this paper summaries the essential causes of tectonic and depositional distribution and influencing factors in Dongying depression and Gaoyou depression in Palaeogene, similar in the whole and discrepant locally.
