Research progress on composition of individual oil inclusion

The composition of individual oil inclusion is significant to the studies of hydrocarbon migration and accumulation; however, how to obtain it accurately is a global problem. Research methods and technologies of individual oil inclusion are reviewed and analyzed through literature research. On the whole, these methods can be summarized as a crushing test, composition estimation and in situ nondestructive analysis. Each method has its advantages and limitations, thus the problem of the composition of an individual oil inclusion has not been resolved completely. Further research is demanded in developing new analytical methods and upgrading research equipment.
