摘　　要：影响低渗透储层产能的因素众多而复杂,因此,正确分析和评价这些因素对于低渗透储层开发有重要的指导意义。排除工程因素影响,从地质因素考虑,重点分析和评价沉积与成岩作用对产能的影响,并利用恒速压汞和核磁共振特殊实验数据对其机理进行剖析。研究表明,高邮凹陷南断阶储层产能主要受后期成岩作用控制,局部小范围内,成岩环境相同的受沉积作用控制,究其机理,南断阶储层主要受压实、胶结、溶蚀等成岩作用形成不同的微观孔隙结构,导致南断阶储层产能显著的差异性。Factors affecting low permeability reservoir productivity are numerous and complex, so the correct analysis and evaluation of these factors, for low permeability reservoir development have important significance. This article excludes engineering factors, from geological considerations, focuses on the analysis and evaluation of sedimentary and diagenetic effects on productivity, and analysis of its mechanism taking advantage of special data such as constant-pressure mercury and NMR. Research indicates that： the storage layer production capacity are mainly controlled by later diagenesis in Sag Gaoyou South broken bands, and controlled by sedimentation in local small scale and the same diagenetic environments, to study its mechanism, reservoir is mainly affected by diagenesis such as compaction, cementation, corrosion in South fault terrace of Gaoyou Sag, to form a variety of micro-pore structure, led to significant differences of reservoir production capacity in South fault terrace of Gaoyou Sag, so diagenetic facies studies for evaluation of low permeability reservoir productivity forecast is significant.
