摘要：

谢家湾构造下三叠统的有机包裹体可分为5种类型,4类组合。各类组合的包裹体均一温度分布具有低→高→较高→低的变化特点,说明嘉陵江组五段经历了浅→深→较深→浅的埋藏历史。根据包裹体的组合分析,该区液态烃的运移应在早燕山期之前,而气态烃的运移则在晚燕山喜山期。

关键词: 流体, 包裹体, 油气运移, 特征, 下三叠统

Abstract:

The fluid inclusions in the fracture filling minerals in the Lower Triassic,Xiejiawan Trap,Dangyang synclinorium,can be classfied into 5 kinds and 4 types of association.In each association type,the homogenization temperatures of the inclusions varied from low to high,then to low and finally to lower temperature again,suggesting the bury depth of the 5th Member of the Jialingjiang Formation changed from shallow→deep→shallow→shallower again.According to the analysis of inclusion composition,the migration of liquid hydrocarbons of the study area should happen before Early Yenshan Period,but the migration of gaseous hydrocarbons started in Late Yenshan-Himalayan Period.
