摘要: 根据基准面旋回和可容纳空间变化原理,研究了东濮凹陷濮城油田沙三上亚段长期、中期、短期基准面旋回,划分出长期基准面旋回1个、中期基准面旋回10个、短期基准面旋回50个,并对三种类型的短期基准面旋回结构特征及分布进行了详细描述.在高分辨率层序地层划分对比的基础上,建立了高精度层序地层格架.利用储层非均质性的层次性及流动单元层次性与基准面旋回级次性的相关性,对储层流动单元进行了划分,为精细储层研究提供了一种新的思路.

Abstract: A high-resolution sequence stratigraphy of oil and gas reservoirs in the Upper S3formation of Pucheng Oilfield is studied by describing cores of wells and analysis of the logging data and seismic data in detail.The sequence strata are divided with the method of high-resolution sequence stratigraphy.The relations among structural types of cyclic sequence,strata response, sedimentary kinetics and their corresponding evolution series,and stacking and preservation condition of sedimentary micro facies are discussed.The strata contrast frameworks of cyclic sequence at different levels are set up.The laws of distribution of petroleum reservoirs,including the relations among the characteristics of geometric pattern,the physical feature of rocks and sedimentary system,the ratio of A/S are proposed.Finally,fifty one reservoir flow units,such as mono type,complex type,and four levels of evaluation of reservoir flow unit,are classified.

Key words: cyclic sequence, framework of sequence cyclic, reservoir flow unit, Sha-3 member, Pucheng Oilfield
