The evolutionary model organic beach or reef reservoir, controlling factors of which are sedimentation, digenesis and tectonics ,are established according to the result of sedimentary facies and digenesis. At last regional distribution of reservoir has been predicted. Comprehensive study indicates the dark, 50-300 m thick upper Permian series, which is rich in the organic material and biota , is beneficial to formation and protection of petroleum and natural gas. Moreover the stratigraphy possess with better reservoir ability. The reservoir distributed in shallow glacis along Beichuan Tongkou - Guangyuan Changjianggou ,He 12 well - She 1 well - Jiange - Cangxi Yongningpu -Long 4 well - Bian 1 well in Wujiaping stage and in platform edge beach along Beichuan Tongkou - Jiangyou Shuigentou - Jiange -Cangxi Yongningpu - Nanjiang .
