摘要
Based on large amounts of data of lithological characters, physical property, pore structure and thin section, the authors paraphrased controlling factors of the reservoir development in combination with sedimentary elements and diagenesis. The results indicate that Denglouku Formation sandstone belongs to braided delta plain subfacies in Changling gas field, composed of feldspathic lithic sandstone, the reservoir space consists in the intergranular dissolved pores, associated with low porosity and permeability. Rock source is the basis of sand bodies. The physical properties of quartz sandstone are better than that of lithic quartz sandstone and lithic sandstone.
