摘　　要：鄂尔多斯盆地东部太原组为典型低孔低渗的致密砂岩储层,有较强的非均质性。基于储层物性、录井和试气资料,综合运用经验统计法和孔隙度-渗透率交会图法,对鄂尔多斯盆地东部太原组有效储层物性下限进行了厘定,并结合沉积相和岩石成分进行控制因素分析,得出该区有效储层主要受沉积相和岩性等因素控制。Taiyuan formation in the eastern Ordos basin is a typical low porosity and low permeability tight sandstone reservoir with strong heterogeneity. The reservoir based on logging data and gas test data, using empirical statistics method and porosity permeability cross plot method of Ordos basin in eastern Taiyuan formation the lower limit of reservoir properties were determined, and combining with the sedimentary facies and rock composition control factors, the effective reservoir in this area is mainly affected by the sedimentary facies and rock composition.
