分析了辽河油田新开地区沙一段和沙三段不同相带、不同地区、不同埋藏深度的储层物性参数特征；研究了这些参数与岩石组分和结构、沉积相带以及埋藏深度之间的关系；对不同物性条件、不同相带、不同地区、不同埋深的储层铸体薄片进行了选择性观察。研究认为：影响该地区储层物性的因素有溶蚀作用、充填胶结作用、压实作用和沉积条件。在这几个因素中，溶蚀与胶结作用是最主要的，对该地区储层物性起了决定性控制作用；压实作用次之；沉积条件只在一定程度上对储层物性有影响。
The characteristics of reservoir physical parameters in different facies belts, different regions and different burial depths in Shahejie Formation and Shahejie Formation of Liaohe Oilfield are analyzed. The relationship between these parameters and rock composition and structure, sedimentary facies belt and depth of burial is studied ; Selective observation on the thin castings of reservoir castings with different physical conditions, different facies belts, different regions and different burial depths. The study shows that: Factors that affect reservoir physical properties in this area are dissolution, filling and cementation, compaction and deposition conditions. Among these factors, dissolution and cementation are the most important factors, which play a decisive role in controlling reservoir properties in the area; followed by compaction; and depositional conditions have an impact on reservoir physical properties to a certain extent.
