摘　　要：建立了内外区流度比影响下的复合地层中气井压力动态分析的有效井径数学模型,利用硫沉积情况下地层渗透率与含硫饱和度的关系,获得不同含硫饱和度影响的气井井底压力解,由该解做出了不同含硫饱和度影响下的用于气井压力动态及试井分析的典型曲线,分析了含硫饱和度对压力动态的影响。该研究为含硫气藏气井的压力动态及试井分析提供了理论基础。The effective well diameter mathematical model is established which is about gas well pressure transient analysis in the composite layer affected by mobility ratio of the inside by outside.Using the relationship of formation permeability and sulfur saturation,the pressure solution at the bottom hole of gas well is obtained affected by different sulfur saturations,and the solution can be used to draw the characteristic curve affected by different sulfur saturations and used to analysis the gas well pressure behavior and well test,and the influence of sulfur saturation on pressure behaviors is analyzed.This research offers the theoretical base of pressure behavior and well test analysis of gas well in sulfur gas reservoir.
