在有机地化研究中，人们越来越认识到含杂元子（Ｓ、Ｏ、Ｎ等）有机化合物的重要性。近年来一些研究者利用色谱－质谱和火焰光度检测等方法对含有机质物进行了分析和研究，但通常由于灵敏度、选择性差和共洗涤性，因此这两种方法不够理想。本文利用近年新开发的色谱－等离体原子发射光谱技术对我国不同环境的原油中的含硫化合物进行了分析和研究。结果表明该技术对有机含硫化合物的分析与检测，具有高的灵敏度和强的选择性，对原油中的含硫化合物能有效地分离和鉴定。初步研究结果表明，不同沉积环境中形成的原油其含硫化合物的分布特征具有明显的差别，海相碳酸盐岩生成的原油具有丰富的含硫化合物，而内陆淡水湖相和沼泽相源岩生成的原油在仪器的检测范围未发现含硫化合物，这将给油一源对比提供一种新的有效手段。
In the field of organic geochemistry, there is a growing recognition of the importance of organic compounds containing dative (S, O, N, etc.). In recent years, some researchers have analyzed and studied the organic matter by using the methods of chromatographic-mass spectrometry and flame photometric detection, but these two methods are generally not ideal because of their poor sensitivity, poor selectivity and co-wash. In this paper, the newly developed chromatography-plasma atomic emission spectrometry was used to analyze and study the sulfur compounds in crude oils from different environments in China. The results show that the technology of organic sulfur compounds in the analysis and testing, with high sensitivity and strong selectivity of crude oil sulfur compounds can be effectively separated and identified. The preliminary results show that the distribution characteristics of sulfur compounds in crude oil formed in different depositional environments are obviously different. The crude oil from marine carbonate rocks is rich in sulfur compounds, while the inland freshwater lacustrine facies and marsh facies No rock-forming compounds were found in the testing area of the instrument because of the crude oil generated from the rock, which will provide a new and effective means of comparing oil sources.
