| 摘 要： | 贵州赤水地区的中浅层陆相碎屑岩油气勘探长期未引起充分重视。通过对实际资料的分析、对比、研究,认为陆相碎屑岩存在侏罗系和上三叠统须家河组两套烃源岩,具有一定的生烃潜力,但气源主要来自于下伏海相地层;沟通气源层与储层的断裂系统的存在对该区的油气成藏相当重要。赤水地区中浅层陆相碎屑岩气藏成藏模式属于深生浅聚成藏组合类型,具有多期运移聚集、喜山期调整成藏的特点。

| Abstract: | Attention has not been paid for a long time to petroleum exploration in the intermediate and shallow terrestrial clastic rock layers in the Chishui area,Guizhou Province.By analysis and correlation of actual data,it is known that in the terrestrial clastic rock,there are two source rock systems of Xujiahe formation of upper Triassic and Jurassic which are of hydrocarbon potential.However gas source is from the underlying marine formation.The fracture system linking source rock and reservoir is extremely important for petroleum accumulation in this area.Gas reservoir in the intermediate and shallow terrestrial clastic rock in the Chishui area belongs to deep source-shallow accumulation type,and is characteristic of multi-stage migration and accumulation,and becoming reservoir in Himalaya stage. |
