Application of isotopic dating in geochronology of hydrocarbon migration and accumulation

Isotopic dating makes the study of hydrocarbon reservoir forming stages change from qualitative to quantitative analysis.The mechanism of isotopic dating and three methods which developed rapidly in recent years have been introduced,including K-Ar,⁴⁰Ar-³⁹Ar and Re-Os.The application principle,test object,advantage and disadvantage as well as practical application of the methods have been discussed,providing effective reference for the application of isotopic dating in geochronology of hydrocarbon migration and accumulation.
