摘要
天然气中的硫化氢(H_2S)是硫的重要资源,许多国家都很重视从含硫天然气中回收硫。我国天然气中普遍含 H_2S,而 H_2S 为剧毒气体,对人体有害,对设备有强烈的腐蚀作用,易堵塞采油气管柱和气层,故开采含硫天然气有别于一般的天然气,在钻井、采气、集输、净化和加工方面均有其特殊性。随着天然气工业的高速发展,含硫气藏愈来愈多,因此研究天然气中硫资源的特点及其开发技术具有现实意义。
Sulphur-bearing gas reservoir is attached importance in the world for sulphur recover from hydrogen sulfide in natural gas.Natural gas in China generally has hydrogen sulfide,which poisons person,corrodes eguipments of oil-gas wells and plugging strings and pay.From conventional gas reservoir,sulphur-bearing gas reservoir has differences in drilling,producing,delivering and purifing.It is of great significance to study the characterstics of sulphur in gas and develope the technology of production with the gas reservoir discovered more and more.
