| 摘 要： | 湖相滩坝砂体作为油气重要储集体类型之一,在中国东部渤海湾盆地古近系断陷湖盆中广泛发育,其形成发育与盆地特定的演化阶段和构造—地貌背景密切相关。文章以济阳坳陷北部为例,根据盆地结构与地貌背景将断陷湖盆滩坝分为开阔湖盆缓坡型滩坝、水下潜山台地型滩坝和潜山凸起周缘型滩坝3种成因模式。不同构造—地貌背景下的滩坝砂体沉积特征与分布规律不同,由此导致隐蔽圈闭类型与成藏特征、成藏潜力与有利勘探区带的差异性。开阔湖盆缓坡型滩坝规模相对较大,物性较好,主要隐蔽圈闭类型为地层超覆圈闭和岩性圈闭,成藏潜力大;水下潜山台地型滩坝发育不整合遮挡圈闭、地层超覆圈闭和岩性圈闭;潜山凸起周缘型滩坝可以形成陆源碎屑与碳酸盐碎屑滩坝2种成因类型,主要隐蔽圈闭类型为地层超覆圈闭和岩性圈闭,成藏潜力相对较小。

| Abstract: | As one of the important reservoir types,lacustrine beach and bar sandbodies are widespread in the Paleogene of Bohai Bay Basin,East China.The formation and distribution of beaches and bars are closely related to the particular structural evolution stage and the geomorphic setting of the basin.Based on the basin structure and paleo-geomorphologic background,beaches and bars in northern Jiyang Depression are categorized into three genetic models,i.e. those on open gentle slope;those on subaqueous burial hill ... |
