摘要
含硫气藏分布广,储量大,但含硫气藏由于硫的存在,在生产开发过程中产生硫沉积,极大地破坏气井产能,因而含硫气井产能一直备受关注。一点法,修正等时试井法等常规试井方法和分析理论是否仍适用于含硫气井目前还缺乏理论依据。基于渗流力学理论,建立了含硫气井在非达西平面径向稳定渗流条件下的二项式产能方程,分析了硫沉积对气井产能的影响,并用现场的实测资料予以验证。结果证明常规试井方法对于含硫气井是适用的,这为含硫气井的试井分析方法提供了理论依据。
The occurrence of sulfur deposition seriously impacts the sulfurous gas well deliverability.For the existing of elemental sulfur,the normal well testing method and analysis theory which whether or not can be applied to the sulfurous gas well should be proved in the theory.Based on the opinion,the sulfurous gas well binomial deliverability equation is established under Non-Darcy radial direction stable transfusion condition,the influence of sulfur deposition on gas well deliverability analyzed as well.The case study proves that the normal well testing analysis method is suitable to sulfurous gas well deliverability analysis,which is a theory foundation to sulfurous gas well testing analysis theory.
