摘　　要：结合储层特征及构造演化史，通过马五1气藏地层水形成机理和控制因素分析，将靖边气田马五1气藏地层水演化过程划分为6个阶段。研究认为马五1气藏既无边水，也非底水，无明显的气水边界。所谓气井产水，是成藏过程中由于受区域构造和储层非均质性影响而形成的局部成藏滞留水。Combining the reservoir characteristics and tectonic history, through analysis of formation mechanism and controlling factors of the formation water in MaS-1 gas reservoirs, evolution process of the formation water in Ma5-1 gas reservoirs of Jingbian Gasfield can be divided into six stages. Researches show that Ma5-1 gas reservoirs have neither side water, nor bottom water, without obvious gas-water boundary. The so-called gas wells producing water is occluded water from the partial formation of reservoirs influenced by regional tectonics and reservoir heterogeneity during formation process of reservoirs.
