| 摘 要： | 鄂尔多斯盆地西南部的西峰油田,是近几年发现的亿吨级大油田。其中白马中区为西峰油田重点区块之一,延长组长8油层组是该区块的主力油层。通过对长8段岩石颜色、沉积构造以及粒度特征的研究,得到沉积相特征。主河道、水下分流河道以及河口坝微相发育的砂层较厚,物性较好,是该区重点开发的主要储层。

| Abstract: | Xifeng oilfield is located in the southwest of Ordos Basin,which is one of the hundreds million tons oilfield discovered in recent years.Mid Baima block is one of the important areas in the Xifeng oilfield,and the Chang 8 Reservoir of Triassic Yanchang Formation is the main reservoir.By the study of color of rocks,sedimentary structure and granularity characteristics of Chang 8 reservoir,the sedimentary facies characteristics are obtained.Based on the study stated above,the sands development in the main channel,underwater distributary channel and mouth bar facies are thick and have good Physicality Characteristic,so it is the main reservoir and the key objective for exploration and development in the Mid Baima block. |
