杭锦旗锦58井区属于岩性气藏,不同岩相的物性参数、含流体特征差异较大,这种差异具有统计规律。本文对杭锦旗锦58井区的沉积相认识分析,主要依据对该区岩石学特征描述、沉积构造条件认识、岩石结构认识、垂向沉积序列认识、相组合和测井相特征分析进行沉积相的识别和划分,并根据这些标志开展相应地层层系的沉积相分析和对比,并在纵向、横向上研究沉积相的特征、类型及其展布规律。在此基础上,对锦58井区盒1储层进行分类评价。
Well Hangjinqi 58 is a lithologic gas reservoir. The physical parameters of different lithofacies and the characteristics of fluid-containing fluids are quite different. This difference has statistical regularity. This paper analyzes the sedimentary facies of Hangjin 58 well area, mainly on the basis of petrological characteristics, understanding of sedimentary structure, understanding of rock structure, recognition of vertical sedimentary sequence, facies assemblage and log facies analysis According to these signs, the stratigraphic sedimentary facies analysis and comparison are carried out. The characteristics, types and distribution rules of sedimentary facies are researched vertically and horizontally. Based on this, the classification and evaluation of Box 1 reservoir in Jin 58 well area are carried out.
