摘　　要：针对苏里格气田部分下古气井产气因含有硫化氢而导致气井开发受限的现状,通过调研国内外脱硫工艺,根据苏里格气田含硫单井分布、分散脱硫和低投资成本等特点,优选氧化铁干法脱硫工艺进行橇装化设计,并采用市场委托服务模式进行现场试验,对试验结果及经济效益进行分析和评价。结果表明:井口含硫天然气经橇装化设备脱硫后含硫量低于20mg/m3,达到净化要求。脱硫剂平均更换周期为34d,现场各项试验参数达到设计要求,橇装化工艺流程设计合理,脱硫效果显著,试验井由关井状态转变为脱硫净化生产状态,经济效益显著。(表2,图1,参5)In view of the situation where the produced gas of part upper paleozoic gas well of Sulige Gas Field is restricted in development due to the presence of hydrogen sulphide, by investigating desulfurization technologies at home and abroad, according to the characteristic of Sulige Gas Field, such as distribution of single well containing sulfur, decentralized desulphurization and low investment cost, etc, this paper preferred skid mounting design with iron oxide dry desulfurization technology, and carried out field tests with a market commissioned service mode, and carried out analysis and evaluation of test results and cost-effectiveness. The results show that the sulfur content of natural air containing sulfur in the wellhead can be less than 20 mg/m3 as after desulfurization of skid-mounting equipment, satisfying purify requirements. The average replacement cycle of desulfufizer is 34 days, all field test parameters can meet the design requirements, and skid-mounting technology design is reasonable, with a significant desulfurization effect. Test wells can be converted from shut-in status into desulfurization and purifying production state, thereby achieving significant economic benefits. （2 Tables, 1 Figure, 5 References）
