摘　　要：近年来,油气地球化学与成藏学科在新技术、新方法和新思路的引领下快速发展,在指导万米深层油气、非常规油气和复杂油气藏的勘探与开发方面发挥了重要作用。其中,金属同位素(非传统稳定同位素)、卤族同位素、高维度稳定同位素(团簇同位素、三氧同位素、多硫同位素及分子内同位素)等非常规同位素体系受到学界高度关注,并成为地球化学学科中发展最为迅猛的方向之一。传统同位素技术进一步升级换代,C、H、O、S、N同位素系列分析技术依然发挥着主要功能;卤族、Si等同位素分析技术正在快速兴起;成藏年代学分析步入油气藏精准定年新时代;新的有机化学分析手段使得新化合物的发现成为可能,而这些新化合物的发现为研究油气成因提供了新证据。随着油气勘探对象的复杂程度提高,对油气地球化学研究的需求将愈加强烈,新技术的研发和应用将是未来油气地球化学与成藏学科科研工作者的重要使命。In recent years,the disciplines of petroleum geochemistry and hydrocarbon accumulation have developed rapidly under the guidance of new technologies,new methods and new ideas,and have played important roles in guiding the exploration and development of ultra-deep,unconventional,and complex oil-gas reservoirs.Among them,the unconventional isotope systems such as metal isotope(non-traditional stable isotope),halogen isotope,and high-dimensional stable isotopes(clumped isotope,triple oxygen isotope,polysulfide isotope and intramolecular isotope)have attracted great attention from the academic community and demonstrate one of the most rapid development directions of geochemistry.With the further upgrading of traditional isotope technologies,the analysis technologies of C,H,O,S and N isotope series are still playing a major role.Halogen and silicon isotopes are emerging rapidly.Geochronological study of hydrocarbon accumulation has entered a new era of accurate dating of oil-gas reservoirs.New analysis methods of organic chemicals have made it possible to discover new compounds,and this discovery has provided a new evidence for studying the genesis of oil and gas.With the increasing complexity of oil-gas exploration targets,it is more urgent to carry out the research of petroleum geochemistry.In the future,the research and development and application of new technologies will be the important mission for researchers in the field of petroleum geochemistry and hydrocarbon accumulation.
