摘　　要：在分析了阳信洼陷烃源岩多种有机地球化学参数的基础上,对其有机质丰度、类型及成熟度进行了研究。结果表明,阳信洼陷沙一段至沙四段上亚段为好—优质烃源岩,沙四段下亚段为差烃源岩。烃源岩有机质热演化划分为3个阶段:未成熟生物气阶段、低熟油生成阶段和成熟油生成阶段。阳信洼陷主力烃源岩在沙三段和沙四段上亚段,这两个层段是今后勘探的重点层段。Based on the analysis of various organic geochemistry parameters, the organic matters abundance.type and maturity were studied in Yangxin depression. The research results show that Es4 to the upper members of Es4 are good source rocks, the lower members of Es4 is poor source rocks. The maturity of source rocks in Vangxin depression are divided into immature biochemical gas.lower mature oil and mature oil. At present exploration, Es3 and the upper members of Es4 are the main source rocks stages in Vangxin depression.
