摘　　要：天然气中硫化氢含量超过 2 %称高硫化氢气。硫化氢极毒 ,人吸入浓度 1g/m3 的H2 S(相当于天然气中含 0 .0 63 %的H2 S)时 ,数秒钟内即可死亡。高硫化氢气仅出现在碳酸盐岩储集层中 ,碎屑岩储集层的天然气中硫化氢含量很低 ,绝大部分在民用标准之下 (2 0mg/m3 ) ,无需脱硫即可使用。高硫化氢气田均分布在碳酸盐岩 硫酸盐岩地层组合中 ,有三种成因 :①高温还原成因 ;②生物还原成因 ;③裂解成因。我国以往在高硫化氢天然气地质和地球化学、硫化氢气井地质、工程和开发系列技术、普及防硫化氢知识、迅速消除硫化氢大范围空气毒性污染方面的研究薄弱 ,建议加强这些方面的研究 ,以科学安全勘探开发高硫化氢气田。图 1参The gas with over 2% H_(2)S is named as a high H_(2)S gas that is highly toxic, and one must die in seconds in case of breathing 1g/m~ (3) H_(2)S that means 0.063% H_(2)S of natural gases. High H_(2)S gas was generated in carbonate reservoirs only. The content of H_(2)S in natural gas is very low in clastic reservoirs, which is mostly under civil standard (20mg/m~ (3)) and can be utilized without de-sulfurization. All the high H_(2)S gas fields are distributed in systems of carbonate-sulfate strata, and generated because of high temperature-reduction, biologic de-acidizing and cracking. We emphasizes here that the researches about to explore and develop high H_(2)S gas fields must be enhanced scientifically and safely since the Chinese are lack of the necessary researches in high H_(2)S geology and geochemistry, (H_2S) gas engineering and exploitation technology, (H_2S) prevention and remove of large-scale H_(2)S pollution.
