The reservoirs of 4^th+5^th-6^th Members of Yanchang Formation in west Mahuangshan were fine sandstone of delta front. The diagenesis in this area had reached A-period of middle diagenetic stage. The mechanical compaction and cementation had resulted in the poor physical property of the reservoir and that was the reason of reservoir lacking primary pores. However, the eluviations by atmospheric water and corrosion by organic acid were helpful to the local reservoir with induced pore. The next step of petroleum exploration and development should be focused on the forecast of favorable areas with induced pore.
