摘要: 环境扫描电镜是国际上根据科学研究的需要在常规扫描电镜的基础上发展起来的一项新技术。文中应用ESEM2020型环境扫描电镜高温台的功能,选用了不同类型的烃源岩样品及分离的生烃组分样品进行了大量的试验对比与分析,观察到了不同样品的产烃现象,初步说明了不同样品的高温生排烃特征,实现了烃源岩在高温环境下生排烃动态模拟的可视化。

Abstract: Environmental Scanning Electron Microscope(ESEM)as a new tool has been used in oil and gas research fields.The main advantage of ESEM is to operate under reduced pressure and to allow the observation of samples containing liquid or at high temperature in the microdynamic process.Samples used in this paper were different types of source rocks such as mudstone,carbonate and coal or different organic matter from source rocks such as kerogen and alga.Some samples producing hydrocarbon can be observed.The results indicated that the ESEM test at high temperature was helpful to simulate the process of hydrocarbon producing.
