| 摘 要： | 包裹体类型和成分的不同反映了油气的不同演化程度和不同的运移期次。根据包裹体的组成和荧光性可将包裹体组合划分为 3种类型 :发荧光的沥青包裹体和盐水气液包裹体组合类型、不发荧光的沥青包裹体和盐水包裹体组合类型、纯盐水溶液及盐水气液包裹体组合类型 ,它们是不同演化阶段油气运移的重要标志。通过对湖北当阳区当深 3井二叠纪—三叠纪海相地层的包裹体组合的研究表明 ,该区存在 3期不同演化阶段的油气运移 ,即中侏罗世早期至晚期的液态烃运移期、早白垩世早期—中期的裂解烃运移期和早白垩世晚期—中白垩世中期的剩余气运移期。这为中扬子地区的海相地层的成藏研究提供了重要依据。 |

| Abstract: | The differences of inclusions in type and composition reveal the differences of hydrocarbons in evolution degree and migration period. Based on the composition and fluorescent characteristics, the inclusions can be classified into three types: the combination of the fluorescent asphalt inclusions and the gas-in-brine water inclusions, the combination of the non-fluorescent asphalt inclusions and the brine water inclusions, and the combination of the pure brine water inclusions and the gas-in-brine water inclusions. They are important indicators of hydrocarbon migration in different evolution degrees. The study on the inclusion combinations in the marine strata of Permian-Triassic of well Dangshen 3 in Dangyang County, Hubei Province confirmed three periods of hydrocarbon migrations, namely liquid hydrocarbon migration during the period from early to late stage of the Middle Jurassic, the pyrolysis hydrocarbon migration during the period from early to middle stage of the Early Cretaceous, and the remaining gas migration during the period from late stage of the Early Cretaceous to middle stage of the Middle Cretaceous. It provides an important basis for the research on the reservoir formation of the marine strata in mid-Yangtze region. |
