包裹体成分特征反映了油气的演化程度和运移期次。本文对银额盆地石炭二叠系4组地层砂岩中的包裹体开展研究，发现研究区包裹体多≤5μm ，呈串珠状分布于石英颗粒裂隙中，以气液两相的状态存在。根据包裹体中甲烷等有机组分的含量及其相互关系对研究区油气运移过程展开研究，认为二叠系至少经历过较高温较高盐度、较低温低盐度等两期油气运移；结合烃源岩热演化史研究，可分别对应二叠纪中期二叠纪末和白垩纪早晚期两期油气运移过程。

The compositional characteristics of inclusions show the evolution and migration stages of oil and gas .Studying on the inclusions in the sandstone collected from Carboniferous Permian of Yin’ e basin ,we find that most of the inclusions are ≤ 5 μm ;and beaded gas‐liquid inclusions distribute in the fracture of quartz grains .Based on the relationship of methane and organic components ,we focus on the hydrocarbon migration process in the study area ,and find out that Carboniferous Permian in the study area experienced two hydrocarbon migration processes : high temperature and salinity and low temperature and salinity .Combined with the hydrocarbon source rock thermal evolution history ,we find two corresponding hydrocarbon migrations :one occurred in the Middle‐Late of Permian ,and the other one in Late Cretaceous .
