Abstract: Karst reservoirs are widely developed in Sichuan Basin. In order to restore the karst paleogeomorphology of Maokou Formation,the studies on drilling core analysis,logging analysis and seismic data interpretation were carried out. The karst paleo-geomorphological features of the Maokou Formation were characterized by well seismic combination,residual thickness method and impression method. The results show that:(1) The Maokou Formation has the paleo-karstic morphology of "high in the west and low in the east". From the west to the east, the paleo-karst geomorphology could be classified into three geomorphic units such as karst highland,karst slope and karst depression,as well as second-level geomorphologic units,such as residual mound,slope,depression and gully.(2) Karst basin are distributed in Guanyuan-Yuanba-Dazhou-Fengjie area,with residual thickness of Maokou Formation of less than 180 m,which is inherited and evolved landform on the basis of Mao-kou rifting trough. There are deep water facies deposits in the rift trough.(3) The area from south of Sichuan to middlenorth is a karst slope. Karsti-fication is well developed,and effective karst reservoirs are well preserved,mainly distributed in karst residual hills and slopes,while most of the dissolved holes in karst gully are filled with mud of Longtan formation.(4) Jiange-Yuanba-Longgang area in northern Sichuan is located at the edge of rift trough, which is shallow high energy platform edge beach facies and an important new exploration field of karst reservoir. The research results are of great theoretical significance and exploration value for the direction of high-quality karst reservoir exploration.

Key words: karst geomorphology, karst reservoirs, Emei Taphrogenesis, Maokou Formation, Sichuan Basin
