H2S含量超过2%的气体被称为高H2S气体，是一种剧毒气体，呼吸1g/m3 H2S（相当于天然气的0.063% H2S），人在几秒钟内就会死亡。只有碳酸盐岩储层才能生成高硫化氢气体。碎屑岩储层天然气中H2S含量很低，大多数低于国家标准（20 mg/m3），可不经脱硫处理直接利用。高硫化氢气田均分布在碳酸盐-硫酸盐岩地层系统中，是高温还原、生物脱酸和裂解作用的产物。强调指出，我国在高硫化氢地质地球化学、硫化氢气体工程与开采技术、大规模硫化氢污染的防治等方面缺乏必要的研究，必须加强高硫化氢气田勘探开发的科学性和安全性研究。
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.
