摘　　要：修正等时试井的传统应用，主要确定气井当前无阻流量。进而制定合理工作制度。实际上，还可以根据延续生产动态资料，分析气井生产动态特征，评价稳产水平和能力；根据压降、压恢曲线解释气层物性参数和气藏工程参数，分析储层类型、非均质性和边界特征，初步计算动态储量等。修正等时斌井成果的广泛推广应用，丰富了气藏动态分析内容，加深了对气藏的认识和评价，提高了动态分析水平。The traditional application of modified isochronal testing is mainly to determine the current open flow capacity, thereby establishing a reasonable working system. In fact, we can analyze the gas well production performance and evaluate the stable production level and capacity, according to the continued production performance information. To explain the physical property of the gas reservoir and engineering parameters, and to analyze reservoir types, heterogeneity and boundary characteristics, and initially calculate the dynamic reserves, according to the pressure drop, pressure build-up curve. Extensive popularization and application of the fruits of modified isochronal testing enrich the content of the dynamic gas reservoir analysis, deepening the understanding and evaluation of gas reservoirs, levels of dynamic analysis are enhanced.
