摘要
与普通气藏相比,高含硫气藏的开发甚为复杂。该类气藏因其硫化氢含量高,随着气藏的开发,地层中元素硫析出、沉积,使开发过程出现一系列复杂问题。通过综合分析,归纳出元素硫的沉积机理以及元素硫沉积对地层的伤害;分析了两种元素硫沉积预测模型;讨论了硫溶解度的计算方法;总结了影响元素硫沉积的各种因素。
Comparing with normal gas reservoir, it is very complicated to exploit the high sulfur gas reservoir. With the exploitation of the high sulfur gas reservoirs, there are many complex problems due to the deposition of the elemental sulfur.The article analyzes the mechanism of the sulfur deposition and the harm to sour gas production for the elemental deposition.It analyzes two prediction models for sulfur deposition and discusses the calculation method of the solubility. Finally, it presents the factors which influenced the sulfur deposition.
