摘要: 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。

Abstract: The petrophysical character of reservoir rocks of different facies, different areas and different depths in Xinhai Area, Liaohe Oilfield was investigated. Analyses were made on the relationship between petrophysical parameters and rock components and fabric, facies and burial depth. Examination was carried out on pore cast thin sections of selected reservoir samples. The results lead to the conclusion that factors affecting the quality of reservoir rocks in the studied area include depositional conditions, compaction, dissolution and post-solution cementation, among which, dissolution and post-solution cementation are most important, compaction is less and depositional condition least.
