摘　　要：本文介绍了胜利油区第三纪期间火山岩的类型和分布状况,在此基础上讨论了禹城凹陷和东营凹陷南坡火山活动对烃源岩生烃作用的影响,认为小规模的火山活动对生烃作用并没有明显的负面效应,但可能改造已形成的油藏。这一认识对含火山岩盆地的油气成藏评价有着重要意义。Based on studies of the types and distribution of lavas erupted during the Tertiary in Shengli Oilfield, the influence of volcanic activities on the generation of hydrocarbons is discussed, with the Dongying depression and Yucheng depression as examples. It is concluded that weak volcanic activities do not affect the generation of hydrocarbons, but may change the characters of crude oil trapped before the eruption. This understanding is helpful to the research on the petroleum trapping mechanism in basins containing volcanic rocks.
