摘要
The authors choose the samples from four different sections in the same sedimentary micro-facies in the Shizhu synclinorium and the around area on the eastern edge of Sichuan Basin, and analyze the controlling factors of the tight sandstone in the Silurian Xiaoheba Formation. Strong compaction and cementation are the main reasons that cause the reservoir tight, whereas dissolution and breakage can improve the physical property of the reservoir and they are the key factors for the high quality reservoir.
