     The analyses of the mode of structural evolution in Qikou sag showed that, graben faulting of Paleogene generate complex half graben-like framework on NW-SE orientation and complex duplex fault graben on N-S orientation in Qikou sag. According to the lithologic oil reservoir types, spatial distribution characteristics and oil accumulation characters in Tanan sag, four kinds of lithologic oil reservoir forming modes are summarized, including the fault terrace-steep slope-break belt, fault terrace-gentle slope-break belt, cliff-steep slope-break belt and inner basin slope, break belt reservoir forming mode of Qikou sag, combining the geological structure characters.
