中文摘要：

直罗油田长2油层组是延长组主力产层之一,结合鄂尔多斯盆地的构造及演化特征,研究直罗油田岩石类型、沉积构造、测井相及砂体展布特征,明确该区主要发育2条分流河道砂体,物源为北东-南西向;并探讨了长2油藏的油气富集规律.结果表明,研究区西北部、西南部水下分流河道砂体与鼻状构造的组合成为研究区的有利聚集区,该研究为类似地区储层沉积微相及油气富集规律的研究具有一定的借鉴意义.

英文摘要：

Chang-2 oil group is one of the main producing layers in Zhiluo oilfield. After analyzing the rock types,sedimentary structure,electrofacies and the distribution of sand bodies of Zhiluo oilfield combined with structural and evolutional characteristics of Ordos basin,oil and gas enrichment regularity of Chang-2 oil group has been studied and it also has been clear that 2 main distributary channel sand bodies develop with NE-SW source direction. The result shows that the combination of the underwater distributary channel sand body and nose structure in the northwest and southwest forms the favorable accumulation area of study area. This study also offers certain references in the sedimentary microfacies and the oil and gas enrichment regularity study for similar areas.
