摘　　要：同位素测年法使油气成藏期研究从定性分析走向定量分析。该文简述了同位素测年的原理,介绍了近年来取得较快发展的K-Ar法、40Ar-39Ar法及Re-Os法,并着重对这3种方法在油气成藏期研究中的应用原理、测试对象、优缺点及在实际中的应用进行了阐述,为同位素测年在石油地质研究中的应用提供了有效的参考。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.
