摘　　要：目前湿法脱硫技术在大型脱硫厂广泛使用 ,单井上则没有使用。但是许多高含硫气井远离脱硫厂 ,要将这些气井的天然气资源开发出来变成可使用的商品气 ,需要投入大量资金修建输气管道将高含硫天然气输送至脱硫厂进行脱硫 ,这就限制了对许多高含硫的中低产量气井的开发。针对这一状况 ,对湿法脱硫技术在单井上的应用进行了研究 ;阐明了单井湿法脱硫的基本原理 ,确定了单井湿法脱硫的工艺流程 ;指出了湿法脱硫技术在单井上的使用需要解决的几个关键技术 ,并在铁浅一井高含硫天然气气井开发上对这一技术进行了使用。结果证明该工艺在单井天然气脱硫方面效果显著 ,能净化出合格的天然气 ,且经济、合理 ,为大量高含硫、中低产量边远气井的开发展现了广阔的前景。At present,the wet process desulphurizi ng technology is widely utilized in large scale desulph urizing plants and not applied in single wells.Many high sulfurous gas wells,however,are far from the d esulphurizing plants.In order to make the natural gas resources exploited from t hese wells be turned into the commercial gas utilized,a great sum of funds ar e needful for building up gas pipeline for desulphurization to transport the hig h sulfurous gas to the desulphurizing plants,which limits the exploitation of th e high sulfurous natural gas in middle low production wells.Therefore it is nec essary to study the application of the wet process desulphurizing technology to single wells.In the paper,the basic principle and technological processing of si ngle well wet process desulphurization are expounded and determined;and several key techniques which need to be solved for applying the wet process desulphuriz ing technology to single wells are pointed out.Through utilizing such a technolo gy in the exploitation of shallow well Tei-1-a high sulfurous gas well,it is pr oved that such a gas desulphurizing technology is economic and reasonable with an obvious effect-being able to get qualified natural gas by purifying,thus opening up a vast range of prospects for utilizing the high sulfurous natural gas resources i n the remote gas wells with middle low production rates.
