摘　　要：黄骅坳陷奥陶系碳酸盐岩厚度大,从烃源岩的有机质类型、丰度、热演化特征等方面评价其基本生烃条件,认为有机质类型好,由于热演化程度较高,残余有机质平均丰度不很高。对系统取样井的奥陶系样品分析结果,其残余有机碳含量大于0.3%的样品占49%,大于0.4%的样品占32%,若恢复其原始有机碳丰度,其值会更高。据此判断黄骅坳陷应存在较好的奥陶系碳酸盐岩生烃层。The carbonate is thickly developed within the Huanghua Depression. The kereogen typing, organic abundance and thermal evolution analyses suggest that the organic matter is good, however, its thermal evolution reaches a higher rank and the samples that residue organic carbon is more than 0.3% are amount to 49%, and more than 0.4% are amount to 32%. If the original organic carbon abundance could be recovered, the abundance would be much higher, so some good Ordovician carbonate source rocks should be developed the Huanghua Depression.
