摘　　要：随着现代分析测试技术的提高,碳同位素在油气地球化学中的应用也越来越广泛。总结了碳同位素在油气地球化学中的应用,这些应用包括:用碳同位素研究来鉴别原油的生成环境和母质类型,对天然气进行成因分类和鉴别,判断天然气的成熟度,进行油气源对比,讨论油气的次生变化,研究油气运移,研究天然气的混合情况和油藏地球化学。With the development in modern testing and analyzing techniques, carbon isotopes have been used widely in oil and gas geochemistry. Recent advances in carbon isotope studies are summarized in this paper, which include identification of source rock type and forming-environment, the genetic type of natural gas, maturity of natural gas, the correlation of oil-gas-source, the alteration of oil and gas, the retracing of second migration of oil and/or gases, the mixing of different natural gases, the application in reservoir geochemistry. Some questions in application of carbon isotope in oil and gas geochemistry are also discussed.
