摘要: 将层序地层学原理运用于陆相断陷湖盆沉积,对东濮凹陷下第三系沙三段进行了地层等时划分及对比,建立了等时地层格架。根据东濮凹陷下第三系沉积时期湖平面变化频繁和地形结构复杂的特点,并结合该凹陷不同构造部位的结构和地层的分布特征,分别建立了构造坡折型、断层缓坡型、二台阶型、断坡高频型等几种层序地层学模式。这些模式可用于预测该地区低位砂体分布状况。

Abstract: Based on the terrigenous sequence stratigraphic methodologies,the cyclic sequence of Shahejie Formation of fault-depressed lacustrine basin in Dongpu Sag is classified in detail,and the strata contrast frameworks of cyclic sequence of member 3 of the formation are proposed.The level of lake surface changed frequently,and the landscape and structure were very complex in period of Paleogene in Dongpu sag.On the basis of those features,several sequence stratigraphic patterns,such as structure-slope break,fault-slope, two-steps and high-frequency types,were developed in consideration the features of composition in different parts of structure and strata distribution. Those patterns can be used to direct the distribution of reservoirs and determine the oil-gas exploration direction in the member 3 of Shahejie formation in Dongpu sag.

Key words: Dongpu sag, member 3 of Shahejie formation, sequence stratigraphic pattern, reservoir distribution
