摘　　要：东坪气田储层裂缝发育,渗流机理复杂,非均质性强,在开发过程中地层产水,影响气田开发效果和采收率。在水性分析、水气比与出水来源的对应关系基础上,结合结合东坪气田产能变化和产水规律等动态资料,建立了利用生产动态资料识别气井产水水源的模式,并附以产气剖面水源识别方法,提高了水源判定的准确度。Of reservoir in Dongping gas field,fractures are developed,the seepage mechanism is complex,and heterogeneity is strong,which results in producing water from formation in the development process affecting the gas field development effect and recovery factor. Based on water feature analysis,the corresponding relationship between water / gas ratio and water source,combined with the dynamic data of capacity change and the water-yielding pattern,the pattern of using the data of production performance to identify water source of gas well is established and attached to gas producing profile recognition method,which improves the accuracy of the water resource.
