摘要
Based on the experimental methods of slice identification,casting slice,scan electron microscope and X-ray diffractions,the characteristics of petrology and diagenesis on reservoir in Shan1 section of Shanxi Formation and He 8 section of Shihezi Formation of Permian system in the east Ⅱ part of Sulige gas field were studied.The result shows that the main lithology of sandstone in this area is dominated by lithic sandstone and lithic silicarenite with low grade of maturity.Diagenesis of sandstone in this area mainly include compaction,cementation,corrosion and alteration.Diagenetic minerals mainly include siliceous mineral,clay minerals and carbonate minerals etc.The highest diagenetic stage reach to period B of middle diagenetic stage.
