| 摘 要： | 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％．

| Abstract: | The formation water distribution of Mawu No.l reservoir in Jingbian area, Changqing gasfield, is of completely different characteristics from common oil/gas reservoirs due to non-edge water andnon-bottom water and is different from those of gas and water in fracture-cavity system. The regional"relative water-rich area" is formed mainly by the effects of regional structure and reservoir heterogeneity. According to the well log, separate zone testing and gas test data and using conventional well log discriminant method and Polynomial self-network approach, producing water zone discriminant standard and gaszone, gas-bearing bed and dry sand as well as gas-water layer discriminants and conditions are given respectively. The coincidence rate of commercial gas zones reaches 97%. |
