摘　　要：在高含硫气藏中随着地层流体的采出,地层压力将会下降,从而含硫天然气中硫的溶解度也会随之下降,造成地层中元素硫的沉积,这使得高含硫气藏不同于常规气藏。针对发生硫沉积的水侵气藏,考虑硫沉积的影响,在物质平衡方法基本原理的基础上,推导并建立受硫沉积影响的高含硫水侵气藏的物质平衡方程,给出了其线性化形式的物质平衡方程式。High-sour gas can be often found in many discovered gas reservoirs.With formation fluid produced,formation pressure decreases in high-sour gas reservoirs.Consequently,the solubility of sulfur will decrease too,resulting in elemental sulfur deposition to make the reservoir unconventional.Considering the effects of sulfur deposition occurring in water-invasion gas reservoir,based on the basic principle of material balance method,this paper not only establishes a new material balance equation but also presents its linearization form.
