摘要

The diagenetic facies of the close sandstone reservoir in the Foreslope-forebulge zones of Foreland Basin in the Western Sichuan were studied in detail by the measures of drill core observation, thin section analysis, SEM analysis and X-ray analysis in the paper. The diagenetic facies in the reservoir were devided into the compaction facies, karst erosion facies, calcareous cementation facies, siliceous cementation facies and chlorite cementation facies. The characteristics of different diagenetic facies are vary, and thereafter the physical property of their reservoir are also different.
