| Abstract: | With the aid of a variety of experimental tools, this paper deals with. the diagenesisand relationship between the reservoir beds with oil and gas associations and diagenesis ofthe dense sandstones from the Xujiahe Formation in western Sichuan Basin,thus resultingin the establishment of the model for diagenesis and porosity evolution and providing animportant basis and information for the formation of the reservoir beds and oil and gas accumulation, in the study area. |
