摘　　要：新场须二气藏储层非均质性强,气藏气水分布复杂,无统一的气水界面,且分布于不同层位。研究表明,该气藏是一个边水气藏,由于储层强非均质性及成岩后生作用导致"残留地层水"的形成,而"残留地层水"杂乱无序的分布结果使得气藏呈现复杂的气水分布。In Xichang gasfield, Xuer reservoir is characterized by strong heterogeneity, complicated gas-water distribution and no uniform gas-water interface. In addition, this interface is distributed at different intervals. Study shows that this reservoir is an edge-water gas reservoir and is formed by residual formation water, which is caused by strong heterogenity and diagenetic epigenesis. However, the residual formation water is distributed in disorder form and this distribution brings about a complicated gas-water distribution.
