隔夹层研究是储层非均质性研究的重要内容，搞清隔夹层在三度空间的展布规律，对于合理划分开发层系、选择开发井网、提高原油采收率具有重要意义．本文对曙二区大凌河油层缓坡浊积岩储层进行沉积学研究和储层非均质性研究，揭示了隔夹层的成因、类型、特征、分布组合特征及空间展布规律，指出连续分布的隔层可作大套开发层系的隔层，条带状分布的隔层可作小范围注采井网开发层系的隔层．探讨了用分形几何识别隔夹层的方法，并对隔夹层进行了质量评价，为研究区选择合理开发层系、制定最佳开发方案提供了依据．
Interlaminar study is an important part of reservoir heterogeneity research. To understand the regularity of interlaminar distribution in the third dimension is of great significance for the rational division of stratigraphic system, selection of well pattern and improvement of oil recovery. In this paper, sedimentology and reservoir heterogeneity study of gentle slope turbidite reservoirs in Dalinghe reservoir of Shu2 area are revealed. The causes, types, characteristics, distribution characteristics and spatial distribution of interbeds are revealed. Distribution of the compartment can be used for a large set of layers of development of the compartment, strip distribution of the compartment can be used for small-scale injection well pattern development well layer. This paper discusses the method of identifying intercalation layer by fractal geometry and evaluates the quality of intercalation layer, which provides the basis for choosing reasonable development layer and developing the best development plan in the study area.
