814 Worden等人的文章《140°C下的热化学硫酸盐还原气体酸化》的主题。(1995)与我们最近的研究是密切相关的。我们研究了克罗地亚德拉瓦凹陷充满凝析油的Stari Gradac气田产出气中硫化氢和其他有机硫化合物(OSC)的来源。根据对储集层岩石、天然气、凝析油和地层水的大量常规和特殊分析结果，以及长期的流体成分监测数据，我们得出结论：斯塔里格拉达克油层(二叠系-三叠系，深度大于3700m)中的硫化物是在硫酸盐岩(硬石膏)存在的情况下，通过热化学还原机制形成的。
814 The subject of the article “Gas Souring by Thermochemical Sulfate Reduction at 140°C” by Worden et al. (1995) is closely related to our recent research. We examined the origin of H2S and other organic sulfur compounds (OSC) in produced gas from gas condensate-filled Stari Gradac field in the Drava depression in Croatia. Based on results of numerous conventional and specific analyses of reservoir rocks, gas, condensate, and formation water, and data from fluid composition monitoring over a long period of time, we concluded that sulfur compounds in the Stari Gradac reservoir (Permian‐Triassic, depths greater than 3700 m) were formed by thermochemical reduction mechanism of sulfate rock (anhydrite) in the presence of
