Abstract: Marine paleo-uplift is referred to as the important field of oil and gas enrichment for medium-lower combination in Chinese superimposed basin, which can be divided into four types: inheriting type, sediment-control type (stratigraphic pinch out and reef beach in the margin of platform), finalized shape in later stage (fault uplifting and extrusion folding), reconstructing type in later stage (faultblock and monoclinal type). Based on the difference between the texture feature and reservoir-forming feature of oil and gas of marine paleo-uplift, four types of reservoir-forming combinations in paleo-uplift are shown as following: in vertical, the reservoir-forming combinations consist of the top, crust of weathering and inner episode ones; in plane, the reservoir-forming combinations include the core of paleo-uplift, upper slope and down slope and deep depressing. The research results indicate that the oil and gas distribution ofmarine paleouplift is featured by complex accumulating, various paleo-uplifts have favorable geologic conditions to discover large oil and gas fields

Key words: marine paleo-uplift, cratonic basin, types of paleo-uplift, reservoir-forming of oil and gas, large oil and gas field
