摘　　要：M气藏为典型的裂缝—孔隙型底水气藏,气井普遍产水影响整体开发效果,而当前缺乏综合有效的分析方法来判识气井出水来源。借助Eclipse数值模拟软件提出了5种有效方法。最后以2口采气井为例,综合运用判识方法准确判断出了单井出水来源。单井出水来源的准确判断有助于后续制定合理的开发对策。M reservoir abroad is a typical fracture - pore type reservoir with bottom water, so the wells always yield gas with water, which affects the welFs overall development effect. However, there exists no comprehensive analy-sis method to accurately obtain the water inrush source. According to related research results about water inrush in gas reservoirs and development data of M gas reservoir, five useful methods are set up with the help of the Eclipse software. Finally, the identification process is illustrated in detail by taking two gas wells in M reservoir. The analy-sis of water production source in individual well is very helpful for making reasonable development measures in future.
