Based on many analytical data such as organic carbon and gas chromatography of saturated hydrocarbon of well QN3 in the Qinan Sag, organic matters in the dark shale of every formation has been evaluated systematically.The result of evaluation is that, in this well, the abundance of organic matter is low in Ed1, moderate in Ed2, and the four formations of Ed3, Es1, Es2 and Es3 have good source rocks.The dominant type of kerogen isⅠ2, but the maturity of shallow layer is low.The depth of oil threshold is 2 900~3 000 m.About the climax of oil generation occurs in 3 400~3 500 m.The depression possesses conditions for commercial oil and gas.Source rock; Comprehensive evaluation; Organic matter; Qinan Sag.
Key words： Source rock; Comprehensive evaluation; Organic matter; Qinan Sag.
