| 摘 要： | 鄂尔多斯南部镇原泾川地区延长组的沉积特征经过多年的资料积累和深入研究，发现在延长期沉积物主要来源于盆地西部的隆起，沉积相类型主要为正常的河流三角洲和湖泊沉积，岩石学特征表明，碎屑颗粒均为颗粒支撑，没有杂基支撑的结构类型，沉积构造组合也表明没有重力流的沉积特征，有利的储集砂体主要为河口砂体和分流河道砂体。

| Abstract: | The data collection and detailed study of sedimentary environment of Yanchang Formation in Zhengyuan and Jingchuan area revealed that the sediments were originated from the uplift in the western Ordos basin.Normal fluvial delta facies and lacustrine facies were the major sedimentary facies of Yanchang Formation.Lithological character indicated that clastic grains were grain supported and free from matrix support.The sedimentary association showed that there was no sedimentary feature of gravity flow.The favourable reservoir sand bodies were dominated by distributary mouth bar and distributary channel sand bodies. |
