摘要
致密砂岩气藏压力恢复测试时间,且难获得径向流直线段,解释参数多解性强。利用长期生产数据,包括产量和压力数据,可以进行生产数据试井分析,和压力恢复试井相结合进行测试资料综合分析可以更准确的提供渗透率、表皮系数、地层压力等参数。以川西致密砂岩气藏一口井为实例,进行了压力恢复试井解释和生产数据试井解释,降低试井解释多解性。
Pressure recovery test time of tight sandstone gas reservoir is difficult to obtain straight line section of radial flow.Long-term production data,including production and pressure data,can be used for well test analysis.Combined with pressure recovery well test,comprehensive analysis of test data can provide more accurate parameters such as permeability,skin coefficient and formation pressure.Taking a well in tight sandstone gas reservoir in western sichuan as an example,the pressure recovery well test interpretation and production data well test interpretation were carried out to reduce the multiplicity of well test interpretation.
