摘要： 以鄂尔多斯盆地中东部某油田长6致密砂岩储集层为例，采用场发射万倍扫描电镜、岩石及铸体薄片观察、压汞、核磁共振等多种实验手段，分析致密砂岩储集层微观孔喉群落分布特征，强调孔喉群落的综合效应对致密砂岩储集层开发的重要影响，认为致密储集层静态地质模型网格单元尺寸无法与微观群落尺寸很好匹配是导致模型可靠性和准确度受限制的根本原因，采用群落平均尺寸能够更直观、准确地表征致密砂岩储集层非均质特征。

Abstract: Taking Chang?6 tight sandstone reservoir in one field of mid?eastern Ordos basin as an example, with many experimental means such as FE?SEM, rock and cast sections, mercury injection and NMR, etc., this paper discusses in detail the pores and throats features in tight sandstone reservoir and suggests that the composite effects of pores and throats are significant to the development of such a reservoir.The static geological model for this reservoir can not well match with the micro?pores and throats by cell unit size, which is the primary cause resulting in limitation of reliability and accuracy, while using mean cell unit size of micro?pores and throats could more directly and properly characterize the heterogeneity of the tight sandstone reservoir
