| 摘 要： | 在目前大多数主力油田已进入高含水期的形势下,分析河道砂内部建筑结构,了解剩余油分布规律,保持油田高产稳产已迫在眉睫。通过高分辨率层序地层学理论作为研究的平台,研究储层内部薄夹层的识别,因为储层内部的物性如孔隙度、渗透率、含油饱和度大小以及剩余油的分布与这些泥质薄夹层的空间分布有着很大的关系。利用高分辨率层序地层学理论,探讨薄夹层的成因及其识别,这对精细表征油藏地质特征,研究剩余油形成和分布,进而采取有效的工程措施都具有重要的地质意义。

| Abstract: | At present,most oilfields have entered the high water phase.And it is thus very necessary to analyze fluvial sand-body architecture,understand residual oil regularities of distribution and make oil fields keep stable production.The authors take the high-resolution sequence stratigraphy as a tool to identify reservoir interbeds.Because physical properties such as porosity,permeability,oil saturation and residual oil distribution are closely related with these mudstone interbeds in the space distribution,our study chose the Changyuan main oil zone in Daqing to discuss the identification of fluvial facies reservoir interbeds. |

| Keywords: | high-resolution sequence stratigraphy fluvial sand body inhomogeneity of reservoir interbeds |
