The Shihezi Formation is the focus point of natural exploration gas layer in Majiatan area of Ordos Basin�� The research on rock characteristics and diagenesis of Shihezi Formation in the Majiatan area indicates that the stone box set of reservoir rock types are mainly quartz sandstone��lithic quartz sandstone and small amounts of feldspar-lithic sandstone�� The main type of reservoir sandstone diagenetic are compaction and pressure solutionquartz overgrowth-cementation-dissolution�� According to the characteristics of diagenesis and sandstone reservoir��a symbiosis of diagenetic sequence is established: authigenic illite-authigenic chlorite-quartz overgrowth-kaolinite-calcite�� Ordos Basin is a CO2 buried potential target area in China�� The petrological saudy on the diagenesis and buried layer section may provide information for numerical simulation of CO2geological research��
