摘　　要：含硫化氢天然气在全球分布广泛。我国目前已在四川、渤海湾、鄂尔多斯、塔里木和准噶尔等含油气盆地发现了含硫化氢天然气。其中四川盆地川东北气区、华北赵兰庄气田和胜利油田罗家气田为高含硫化氢气田。在对国内外硫化氢研究现状分析和对硫化氢成因机理、成因类型和高含硫化氢气田地质特征研究的基础上,认为上述3个高含硫化氢气田的硫化氢均主要为硫酸盐热化学还原成因(ThermochemicalSulfateReduction,TSR)。Reservoirs of hydrogen sulfide bearing gas are distributed widely in globally. The natural gas with H_2S content have been discovered in several petroliferous basins of China which include Sichuan, Bohai bay, Erdos, Tarim and Zhungaer, etc. Among them, the north-eastern gas area of Sichuan basin and the Zhaolanzhuang gas field located in North China, together with the Luojia gas field located in Shengli oil field of eastern China, are all belong to gas fields with high H_2S contents. According to the analysis and summary of the current research status of H_2S at home and abroad, based on the probing into the genetic mechanism of H_2S and its classification and combining the geological features of the gas fields with high H_2S content, it can be concluded that the above three gas fields were originated mainly from the thermochemical sulfate reduction (TSR).
