| 摘 要： | 目的 评价禹城洼陷的生烃潜力，以指导下一步勘探。方法利用烃源岩分析数据对禹城洼陷的生烃潜力进行研究和评价，利用包裹体测温等分析资料对影响烃源岩发育和分布的因素进行分析和总结，利用生物标志化合物指标（C29S／S＋R）对生油门限进行了重新认识和探讨。结果禹城洼陷烃源岩发育较差、分布不均，总体上处于未熟一低熟阶段；其主要影响因素是异常高压带的分布和火成岩的入侵；本区生油门限应在3500m以下。结论禹城洼陷下第三系生烃潜力不足。

| Abstract: | Aim Further to make the genetic potential of Yucheng Depression clear, and guide next exploration. Methods Utilize the analysis data of source rock to research and estimate the genetic potential of Yucheng Depression, utilize the temperature measurement data of inclusion to analyze and conclude the factors affecting the development and distribution of source rock, utilize biomarker index to newly recognize and discuss the oil threshold. Results The source rock in Yucheng Depression Poorly developed and unevenly distributed. As a whole it was in an immaturity to low maturity stage, the main influencing factors were the distribution of abnormal pressure and the invasion of igneous rock. The oil threshold in this region is under 3 500 m. Conclusion The genetic potential of Yucheng Depression is deficient. |
