摘要 储层原始含油饱和度是评价储层的重要参数,一般是通过压汞资料得到的毛管压力曲线来求取该参数。然而,在具有相同进驱力时,微观孔隙结构对含油饱和度的影响起到了非常大的作用;同时,通过理论分析所得,储层品质指数是定量表征储层微观孔隙结构的最佳宏观物性参数。研究基于储层品质指数对岩心分析数据进行分类,进而利用毛管压力曲线求取储层原始含油饱和度,最终应用于其它储层。 The original reservoir oil saturation is an important parameter to evaluate reservoir. We can strike it through the use of mercury capillary pressure curve calculation. However,with the same force into the drive,the influence of microscopic pore structure on oil saturation has played a very important role; at the same time,proceeds through theoretical analysis,reservoir quality index is the best macroscopic properties parameters to quantitative characterization of reservoir microscopic pore structure. So this article based on reservoir quality index to classify routine core analysis data,and thus the use of capillary pressure curve to compute the original reservoir oil saturation,then applies to the other reservoirs.
