天然气中的硫化氢分别起源于生物化学作用、热化学作用、岩浆作用。含硫有机化合物的热分解和硫酸盐的热还原,是硫化氢的最主要来源。

HS in natural gas can be produced by biochemical process, thermochemicalprocess or magmatism. The decomposition of sulphur-bearing organic matter andthe reduction of sulfate in higher temperature are the main geneses of HS. Si-mulating test made by the authors indicates that sulfate can produce HS inhigher temperature. Some evidences found in rock samples show that carbonateand pyrite replaced anhydrite and formed HS. It is predicted that natural gasat the depth of 3600-6600m in the Jiyang Depression has the highest contentor HS.
