摘要
高邮凹陷南断阶低渗透储层同一沉积微相产能差异变化大。利用铸体薄片、阴极发光、扫描电镜等资料,对高邮凹陷南断阶阜宁组储层成岩作用类型及特征进行了综合研究,在此基础上结合实际生产应用,将研究区阜一段储层划分为弱压实成岩相、中等压实胶结成岩相、中等压实溶解成岩相、强压实胶结成岩相和强压实溶解成岩相5种成岩相类型,建立了不同类型成岩相测井曲线特征,确定了不同成岩相的定量判别标准,利用判别标准定量识别研究区阜宁组阜一段储层成岩相,结合产能评价有利成岩相。
The productivity of the same sedimentary microfacies have significant difference in the south section of Gaoyou fault low permeability reservoir. Therefore, the study of diageneticfacies is important to low permeability reservoir, in current development phases. Based on data of cast-slice, cathodeluminescence and SEM analyses data, the present paper comprehensively investigats types and characteristics of reservoir diagenesis of the formation in the south section of Gaoyou fault, distinguishs types of diageneticfacies combining practical production. The reservoir of the first segment formation could be divided into five types of dia＇genticfacies including slight compacted facies, middle compacted-cemented facies, middle compacted-corroded facies, intensively compacted-cemented facies, intensively compacted-corroded facies. We discuss logging curve features of different diagenetic facies, establish the quantitative recognition criteria and using the recognition criteria, we recogniz the diageneticfacies of the first segment Funing formation diageneticfacies. Combining the productivity, we also determine beneficial diageneticfacies.
