稳定同位素地球化学是发展较快的学科之一，七十年代起被广泛应用于油气地球化学研究中。本文综述了碳稳定同位素在油气地质研究中的应用和进展，这些应用主要包括确定源油的形成环境与形成时代；进行油／油、油／源对比；判别天然气的成因类型并进行对比；判断天然气的成熟度。
Stable isotope geochemistry is one of the fastest growing disciplines. Since the 1970s, it has been widely used in petroleum geochemistry. This review summarizes the applications and advances of carbon stable isotopes in the study of petroleum geology. These applications mainly include determining the formation environment and forming age of source oil, comparing oil / oil, oil / source, discriminating natural gas types and comparing them Natural gas maturity.
