| 摘 要： | 榆林气田陕151井区山西组二段储集层是实现增储上产的主力产层。影响该区天然气富集高产的主要因素:石炭—二叠系煤系烃源岩提供了丰富的生气母质,在低孔、低渗背景上发育了多期水下分流河道石英砂岩和岩屑石英砂岩有效储层,在平缓构造背景上发育的低幅度鼻隆构造带严格控制着气、水分布;山西组顶部发育的浅湖相泥岩提供了良好的盖层条件。

| Abstract: | The reservoir rocks in the second member of Shanxi Formation occur as the major reservoir rocks favourable for gas accumulation and high production in the Shaan-151 well area,Yulin Gas Field,Ordos Basin.The controlling factors include: abundant gas-generating mother material derived from Carboniferous Permian source rocks;multiphase subaqueous distributary channel quartz sandstone and lithic quartz sandstone as effective reservoir rocks;restricted gas and water distribution constrained by slightly uplifted structural zones,and excellent seal rocks represented by shallow lacustrine mudstone at the top of the Shanxi Formation. |
