摘要:During the development process of high sulfur gas reservoir, as the decline of producing energy, hydrogen sulphide is de⁃composed and sulfur particles are precipitated, furthermore, sulfur deposit is formed, which causes formation pollution. According to sulfur pollution area and no sulfur pollution area in high sulfur gas reservoir, well test interpretation model for dual media gas res⁃ervoir is established. Taking into account influential factors of wellbore storage factor, skin factor, effective radius and wellbore flu⁃id phase separation, this model solves bottom hole pseudopressure solution in infinite gas reservoir. Finally, by using Stehfest nu⁃merical inversion and Matlab software, log-log graph of bottom hole pseudopressure and pseudopressure derivative is obtained, in addition, the influence of factors such as phase distribution pressure parameter, sulfur saturation, radius of sulfur deposition, inter⁃porosity flow coefficient, and storativity ratio on well test curve is analyzed. The research has important theoretical and practical sig⁃nificance.%在高含硫气藏的开发过程中,随着地层能量的不断下降,硫化氢会分解,硫颗粒析出,最终形成硫沉积现象,对地层造成污染。针对高含硫气藏中的硫污染区和未污染区,建立了双重介质复合气藏试井解释模型。该模型考虑了井筒储集系数、表皮系数、有效井径及井筒流体相分离等因素的影响。求解了无限大气藏的井底拟压力解。最后利用Stehfest数值反演及Matlab软件,获得了无限大气藏井底拟压力及拟压力导数的双对数曲线图版。同时,分析了相再分布拟压力参数、含硫饱和度、硫沉积半径、内外区窜流系数、内外区弹性储容比等因素对试井曲线的影响。研究内容及结果具有较强的理论性及现实意义。
