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 5 0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。
According to the theory of reference plane gyration and space-changeable principle, the long, medium-term and short-term cycles of the upper third member of Pucheng Oilfield in Dongpu Depression are studied. One long-term reference cycle, one medium cycle reference cycle, There are 50 cycles of datum, and the structure and distribution of the three types of short-term cycles are described in detail. Based on the high-resolution sequence stratigraphic division and contrast, a high-precision sequence stratigraphic framework was established. The division of flow units in reservoirs by using the stratigraphy of reservoir heterogeneity and the correlation between the flow unit level and reference level swirling order provides a new idea for the study of fine reservoirs.
