摘　　要：受层间非均质性等影响,多层气藏表现出层间日产气量差异大、各小层出水顺序及产水量也不相同的情况,采用常规方法无法了解每个小层的生产状况。对产气剖面测试成果在多层气藏动态分析中的应用进行了系统梳理,以台南气田F气藏为例,阐述了产气剖面可用于了解单井分层产气量及其随时间的变化、确定各小层的无阻流量、识别各小层出水顺序与出水量、分析整个气藏的分层产量贡献与剩余气分布。分析表明,通过有计划、系统地测试产气剖面,可以准确认识多层气藏的动态特征,优化确定科学的开发技术政策,提高气藏开发效果。该分析对多层气藏开发动态监测优化设计与动态分析具有借鉴意义。Due to the heterogeneity among layers,the daily gas production,the order of water out,and the volume of water produced in each layer of a multi-layer gas reservoir are different.However,conventional methods cannot obtain the production status of each layer.This paper systematically collates and analyzes the application of gas production profile test results in the dynamic analysis of multi-layer gas reservoirs.Taking the F gas reservoir in the Tainan Gas Field as an example,the gas production profiles can be used to understand the gas production of each layer in individual wells and their changes over time,determine the open flow capacity,identify the order of water out,analyze the production contribution of each layer as well as residual gas distribution of the entire gas reservoir.The analysis shows that by systematically testing gas production profiles,it is possible to accurately recognize the dynamic characteristics of multi-layer gas reservoirs,optimize development technology plans,and improve gas reservoir development effect.Which has important guiding significance for dynamic monitoring optimal design and dynamic analysis of multi-layer gas reservoirs development.
