| 摘 要： | 根据岩性、铸体薄片、物性、孔隙结构等分析化验资料对鄂尔多斯盆地定边地区延安组延10储层特征的研究结果表明:延10储层岩性主要是岩屑长石砂岩,其次是含长石石英砂岩以及长石砂岩;储集空间以剩余原生粒间孔、粒间溶孔为主,属于中孔低渗储层,渗透率变化范围较大;储层属中孔细喉型,排驱压力和中值压力较低. |

| Abstract: | Based on some data from lithological,casting thin-section,physical property and porous structure analysis,a systematically study on reservoir characteristics of Yan 10 Member is implemented.Results illustrate that:(1) the reservoir is mainly composed of debris feldspar,partly quartzose sandstone with feldspar and feldspar sandstone;(2) its space mainly includes residual primary intergranular pore and dissolution pore;(3) it is featured by middle porosity and low permeability,large variation in permeability;... |
