摘　　要：高含硫气藏随着开采的进行,元素硫会从天然气中析出,沉积到地层中的元素硫会堵塞孔道,减小流体流动有效空间,并降低地层渗透率,使得流动阻力增大,给气井的正常生产带来严重的伤害。文中给出了预测硫沉积的平面径向流模型及裂缝硫沉积模型,根据模型得出了硫沉积对储层的伤害规律,为合理开发这类油藏提供科学依据。As the high sour gas reservoirs are put into production, the elemental sulfur is separated from natural gas and the deposited elemental sulfur will block the pores, which will decrease effective flow space, decline permeability and increase flow resistance. All of them will affect seriously the normal production of gas wells. Some prediction models of sulfur deposition are given and the distribution law of sulfur deposition can be obtained in this paper. It also analyzes the formation damage caused by sulfur deposition according to models, which offers scientific foundation for the development of similar gas reservoirs.
