VISUALIZATION TECHNIQUE OF SOURCE ROCKS PRODUCING HYDROCARBON PROCESS AT HIGH TEMPERATURE BY MEANS OF ENVIRONMENTAL SCANNING ELECTRON MICROSCOPE

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.
