摘要

摘要: 利用岩石薄片、铸体薄片、孔渗分析等实验手段，对苏北盆地金湖凹陷阜二段砂岩储层的矿物岩石特征、储层物性特征、孔隙结构特征以及储层物性的主要影响因素进行了相关分析。研究表明，阜二段储层岩石颗粒总体偏细，不同地区岩石成分成熟度均值差别小、范围值都较宽；西部斜坡带储层物性相对较好，其他地区以低孔、低渗—特低渗储层为主；压实和碳酸盐胶结是导致储层物性变差的主要原因；溶蚀作用和油气充注是抑制物性变差、改善储集性能的重要因素。西部斜坡带等地区是储层物性相对较好的有利地区。

Abstract: The lithologic characteristics of minerals, reservoir physical properties and pore structure of sandstones in the second member of Funing Formation in the Jinhu Sag of Subei Basin were studied based on petrographic thin sections, casting thin sections, porosity and permeability, and the influencing factors for reservoir physical properties were discussed. The sandstones in the second member of Funing Formation are generally fine grained. The average maturity of rock composition is similar among different regions, and range widely. The sandstones on the western slope of Jinhu Sag have better physical properties while those in the other areas are featured by low porosity and low to extra low permeability. Compaction and carbonate cementation are the main reasons leading to poor reservoir physical properties. Dissolution and hydrocarbon filling are important factors to restrain diagenesis and improve reservoir characteristics. The western slope has relatively better porosity and permeability and is a favorable target for hydrocarbon pools.
