摘要
针对GY油田长6和长4+5油层组特低渗储层成岩过程中压实和胶结作用强烈,成岩阶段和成岩作用复杂的特点,通过研究其储层成岩过程中岩性和物性特征、孔隙演化的基本规律以及孔隙类型、孔隙结构特征等,在研究区划分出了4种类型的成岩储集相,并确定了各类成岩储集相测井曲线响应特征。通过实例分析了特低渗储层不同成岩储集相的测井曲线异常差异,并有效划分了成岩储集相类别,为油田有利含油区块筛选及后期的高效开发提供了依据。
The extra-low permeability reservoir of Chang 6 and Chang 4+5 reservoir in GY Oilfield has the characteristics of intense compaction and cementation, complicated diagenesis and diagenetic process. Based on the analysis of the lithology and physical properties, pore evolution, pore types and pore structure features, this paper classified the diagenetic reservoir facies into four kinds in this area, and determined the log response features of each kind of diagenetic reservoir facies. This paper also analyzed the log response features diversity of different diagenetic reservoir facies in extra-low permeability reservoir by case analysis, and classified diagenetic reservoir facies effectively which can provide effective guidance for screening the oil-bearing zones and further efficient development.
