摘要
以新疆三塘湖盆地侏罗系储层中次生流体包裹体研究为例,依据流体包裹体的岩相学、盐度、均一温度以及伴生烃类包裹体等特征,结合盆地热史和烃源岩成熟史研究,认为侏罗系裂缝中的次生包裹体是不同流体来源、不同时期作用的产物,并且侏罗纪末可能存在深部地层高温流体沿裂缝向上运移的热事件。在理清包裹体流体来源的基础上,储层次生流体包裹体不但可以指示油气运移的信息,也可提供地质历史中的热事件信息。
Chosing the Santanghu Basin in Xinjiang as an example, according to secondary fluid inclusions＇ facieology, salinity, sions in Jurassic reservoir, homogeny temperature and character of associated hydrocarbon fluid incluit is believed that the inclusions in the crack of quartz have formed at different fluids process and of different periods com ng with the study of thermal evolution of the basin. The analysis show that there exist a heat event at the end of Jurassic, cordingly, the fluid inclusions have great significance in migrating by cracks from the deep stratum. Acanalyzing of the information about hydrocarbon migration, at the same time, it can provide heat events in geol the characteristics of multi-origin and multi-period, which are c rity history of hydrocarbon source rocks in basin. og rit ca ca 1 history. The fluid inclusions bear 1 in studying the thermal and maturity history of hydrocarbon source rocks in basin.
