随着现代测试分析技术的发展，碳同位素在油气地球化学研究中得到了广泛的应用。本文综述了碳同位素研究的最新进展，包括烃源岩类型与形成环境的识别、天然气成因类型、天然气成熟度、油气源对比、油气蚀变、油气二次运移的追溯、不同类型天然气的混合、油气藏地球化学研究等。并对碳同位素在油气地球化学应用中存在的问题进行了讨论。
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.
