摘要
The base-level change and the inter-architectures of meandering river sands,especially the relationship among the base-level change and the development degrees of intercalations and the intercalations occurrence were researched by using the high-resolution sequence stratigraphy and the reservoir architecture element analysis.The conclusions are as follows: The NmⅡand NmⅢ oil groups develop three complete mid-term base-level cycles,two incomplete mid-term base-level cycles,twelve short-term base-level cycles and nineteen ultra-short term base-level cycles.The types of the base-level cycles can be divided into upward-deepening and upward-shallowing asymmetry,incomplete symmetry dominated by uprising,and nearly complete symmetry.
