摘要
Abstract
Chang 8 of Z block in Ordos Basin is of low porosity and permeability sand reservoir .The main rock type is middle-fine grained lithic arkose sandstone and feldspar debris sandstone .Contact methods are line contact and point -line contact .The main pore types are secondary porosity .It is typical low porosity -special low porosity and ultra low permeability -ultra low permeability reservoir .According to cast flake ,SEM ,EMP and Percolation experiment ,we think that the main experience of the research area is the compaction ,cementation and dissolution .The research area is in the medium diagenesis A phase .The characteristics of low porosity and permeability of sandstone reservoir in Z block are determined by multiple factors diagenesis superimposed effect .关键词
