Over time, stable isotopes have proven to be a useful tool in petroleum geochemistry. However, there is currently insufficient literature on stable isotope geochemistry of the organic elements within shales and crude oils in many petroleum systems around the world. As a result, this paper critically reviews the early and recent trends in stable isotope geochemistry of organic elements in shales and crude oils. The bulk and compound-specific stable isotopes of H, C, and S, as well as their uses as source facies, depositional environments, thermal maturity, geological age, and oil-oil and oil-source rock correlation studies, are all taken into account. The applications of the stable isotopes of H and C in gas exploration are also discussed. Then, the experimental and instrumental approaches to the stable isotopes of H, C, and S, are discussed.
随着时间的推移，稳定同位素已被证明是石油地球化学中的一种有用工具。然而，目前在世界上许多石油系统中，有关页岩和原油中有机元素稳定同位素地球化学的文献还不够充分。因此，本文批判性地回顾了页岩和原油中有机元素稳定同位素地球化学的早期和近期趋势。本文考虑了 H、C 和 S 的整体和特定化合物的稳定同位素，以及它们作为源相、沉积环境、热成熟度、地质年龄以及油-油和油-源岩对比研究的用途。还讨论了 H 和 C 稳定同位素在天然气勘探中的应用。然后，讨论了 H、C 和 S 稳定同位素的实验和仪器方法。
