摘　　要：储层微观孔隙结构是决定储层储集性能及渗流特征的关键因素，分析其成因类型及分布规律，对深入研究储层特征差异及预测优质储层具有重要意义。通过分析姬塬地区长6储层微观孔隙结构特征，结合沉积及成岩作用，将该区长6储层孔隙结构分为6种成因类型，不同类型其储层孔隙结构几何形态、润湿性、储集及渗流等特征不同。不同孔隙结构类型是不同沉积、成岩作用形成，通过研究成岩相分布，可以预测不同孔隙结构类型平面分布及相应的储层特征，为石油勘探开发生产提供依据。The microscopic structure of pores in reservoirs is the key factor to determine the reservoir properties and percolation characteristics. The analysis of the genesis types and distribution law of the pore structure is of great significance to the study of reservoir characteristics differences and prediction of high-quality reservoirs. The pore structure of the Chang6 reservoirs in the Jiyuan area is divided into six types based on the analysis of the microscopic pore structure characteristics of the Chang6 reservoirs, and combined with the sedimentation and diagenesis. For different types of reservoirs, the geometry of the structure, wettability, reservoir characteristics, and percolation characteristics of the pores are all different. Different types of pore structure are formed by different sedimentary and diagenetic processes. By studying the distribution of diagenetic facies, we can predict the plane distribution of different pore structure types and the corresponding reservoir characteristics, and provide the basis for oil exploration and production.
