长庆气田靖边区马五１储集层中地层水的分布与一般油气藏完全不同，既非边水，也非底水，也不同于缝洞系统中的气、水分布特征。区域“相对富水区”的形成主要受区域构造和储集层非均质性的影响。根据马五１储集层的测井、分层测试及试气资料，利用常规测井判识方法和多项式自组织网络方法，分别建立了出水层判识标准和气层、含气层＋干层、气水同层＋水层的判别式及判别条件。其判识效果良好，工业性气层判别符合率达９７％．
The distribution of formation water in the Ma5-1 reservoir in Jingbian area of Changqing gas field is completely different from the general oil and gas reservoirs. It is neither the edge water nor the bottom water or the gas and water distribution in the fracture-cave system. The formation of “relatively water-rich area” in the area is mainly affected by the regional structure and reservoir heterogeneity. According to logging, stratification test and test gas data of Ma5-1 reservoir, using conventional logging identification method and polynomial self-organizing network method, the identification standard of effluent layer and the criterion of gas layer, gas-bearing layer and dry layer , Gas-water layer + water discriminant and discriminant conditions. The discriminating effect is good, and the discriminating rate of industrial gas layer reaches 97%.
