摘要
储层性质的好坏直接影响到油层的产能,注水效果及石油采收率。对濮城油田沙一段储层的非均质性从层内、层间、平面的非均质性三个方面作了系统研究,该区储层的非均质程度以严重非均质型为主,层内夹层多,层间非均质性强,层间隔层分布稳定,平面非均质性较强,油田开发以层内矛盾为主,所以研究层内非均质特征能为揭示砂体展布及合理划分开发单元,选择注采系统,为改善油田的开发效果,进行二、三次采油提供可靠的地质依据。
Reservoir character has a direct influence on recovery factor. A systematical study indicates that the 1st sandstone Member in the Pucheng Oilfield is characterized by strong inhomogeneity and stable impermeable formation which provides scientific base for reasonable petroleum recovery.
