摘　　要：靖边气田低含硫天然气成因问题一直认识不清。综合全烃分析、测井解释、产水、试验模拟等资料,对靖边气田H2S的生成机理、反应条件、控制因素等进行了研究。以此为基础,对靖边气田低含硫天然气的成因进行了探讨。研究表明,靖边气田H2S为硫酸盐热化学还原反应成因,地层水是该反应进行的关键,H2S生成过程始终受地层水控制,气田天然气低含硫的原因并非石膏少,而是地层水有限。研究揭示地层水分布的局限性可能是形成我国低含硫气田的一个重要机制。The recognition of low sulf-gas generation in Jingbian Gas Field was not clarified. Through the analyses of full hydrocarbon, well logging, yielding formation water and experiment, research for the causes of formation, condition of reaction, factor of control on low sulf-gas were studied.Base on these,the low sulf-gas generation in Jingbian Gas Field was discussed. .The research indicates that, thermochemical sulfate reduction is the origin of sulfureted hydrogen of Jingbian Gas Field, formation water is reactive and manipulative factor of sulfureted hydrogen. The low sulf-gas generation isn't few gypsum, but few formation water.Research shows that, the localization of formation water is important mechanism of low sulf-gas.
