Abstract: The organic-rich shales of Niutitang Formation are well developed in Ningqiang Bay,the northwestern margin of Upper Yangtze platform,and they have good oil and gas generation conditions, nevertheless,no investigation and evaluation for shale gas has been carried out in this area. Based on field geological survey and sample test,the thickness,distribution characteristics,depositional settings and organic geochemical characteristics of shales of Niutitang Formation were investigated. The results show that the cumulative thickness of organicrich shales is up to 108.5 m;the mass fraction of total organic carbon is 0.08%-7.54% with an average value of 1.97%;kerogen is type Ⅰ;the Tmax ranges from 419 ℃ to 496 ℃ with an average value of 448 ℃;and the average Ro is 2.36%. These data show that the source rocks have entered into mature to high mature stage. The source rocks are influenced by complex palaeogeography in Ningqiang Bay,and the source rocks on the west side are better than that on the east side,with good prospects for shale gas exploration.
