摘　　要：伊通盆地莫里青断陷储层发育六种孔隙类型,其中以溶蚀粒间孔隙、溶蚀粒内孔隙和填隙物内孔隙为主。孔隙结构类型主要有四种,以ⅢA、ⅢB级为主。研究表明在相同的成岩作用条件下,本区沉积相带控制着孔隙结构的平面分布特征;而在同样的沉积环境控制下,成岩作用对储层孔隙结构的纵向发育特征有着重要的影响。There are six types of pores in the Shuangyang Formation Reservoir in Moliqing Fault Depres sion, dominant by dissolution intergranuler porosities, dissolution intragranular porosities and matrix porosities types. There are four types of porosity texture in which ⅢA and ⅢB are found often. It suggests that under the same diagensis condition, the sedimentary facies control the distribution of porosity texture, whereas the diagen sis influences the characteristics of porosity texture in the vertical direction under the same sedimentary facies condition.
