| 摘 要： | TSR反应的发生可能是造成地质体中天然气耗竭的主要原因之一,其中金属硫化物的生成是TSR反应系统中碳硫氧循环的重要连接体。对H2S-Fe2O3反应体系进行了模拟实验研究,通过X-射线衍射分析手段确定了反应的途径,考察了反应的热力学和动力学特征,计算了反应过程的动力学参数,并初步探讨了反应机理。结果表明,该反应在热力学上是可行的,能够自发进行,生成以FeS2为主的含铁多硫混合物,水介质的存在有利于反应的进行。

| Abstract: | Organic inorganic reactions in the process TSR (Thermochemical Sulfate Reduction) are the main reasons to result in hydrocarbon disappearance. Metal sulfide formation is very important in geochemical cycle of C S O system. In this paper, thermal simulation experiments were carried out using autoclave at definite temperature and pressure. The properties of the products were characterized by X ray diffraction method to investigate the reaction pathway. The thermodynamics and kinetics of H 2 S Fe 2 O 3 systems were discussed. It is found that H 2 S Fe 2 O 3 reaction can proceed spontaneously and increasing temperature is disfavored for H 2 S Fe 2 O 3 system. The products of H 2 S Fe 2 O 3 systems were complex Fe S materials and the primary compound is FeS 2 . On the basis of the experimental data, the reaction mechanism was discussed tentatively. The study on the formation of ferric sulfide in the TSR system for the carbonate rock is a novel way to explain the organic inorganic reactions in deep environment. Further research on this subject is necessary in the future to understand more details of the TSR system and issue of hydrocarbon destruction in gas reservoirs. |
