摘　　要：目前普遍认为天然气藏中硫化氢主要为生物硫酸盐还原(BSR)、硫酸盐热化学还原(TSR)和含硫化合物热裂解等成因。一般认为,天然气中高含硫化氢是硫酸盐热化学还原作用的结果。从气藏的地质和地球化学等方面,可以找到气藏发生硫酸盐热化学还原作用后的许多证据,根据这些证据,可以很好地判断气藏是否发生过硫酸盐热化学还原作用。尽管对天然气藏中硫化氢研究已取得一定的成果,但仍存在许多亟待认识的问题,如硫化氢的成因机理、分布规律、地质-地球化学特征,硫化氢与油气的关系,以及硫化氢形成的主控因素等。总结了国内外关于硫化氢天然气成因研究进展及其存在的问题,以期引起人们对硫化氢天然气的关注。Hydrogen sulfide is one of the common harmful non-hydrocarbon components which appear in marine carbonate gas reservoir.At present,it is generally believed that biological sulfate-reducing（BSR）,thermochemical sulfate reduction（TSR） and thermal cracking of sulfocompound are the main causes of H2S in natural gas reservoirs.In addition,thermochemical sulfate reduction was thought to be the reason of reservoir with high content of H2S.According to the geological condition and geochemical characteristic in gas reservoir,it is easy to find out lots of evidences for the happening of thermal sulfate reduction,by which if the thermal sulfate reduction happened in a gas reservoir can be judged.However,there exist many problems to be solved in the researches on H2S in gas reservoirs,including the genesis mechanisms,distribution pattern,characteristics of geology and geochemistry of hydrogen sulfide,as well as the relationship between hydrogen sulfide and hydrocarbon,the main controlling factors of forming hydrogen sulfide,etc.This paper summarizes the research progress on hydrogen sulfide genesis and existing issues at home and abroad,so that the hydrogen sulfide reservoirs could be more concerned.
