| 摘 要： | 针对B储气库运行10年尚未达到设计能力的事实,设计室内实验获得气水两相相对渗透率曲线,应用产量不稳定分析方法获得井控储层参数,计算井控储层气水两相的相对渗透率,用图解法计算井控储层的平均含气饱和度。分析采气井生产动态,发现水气比和含气饱和度在全库中的变化趋势具有一致性,从而验证了平均含气饱和度计算方法的可靠性。

| Abstract: | Based on the fact that B gas storage has not yet reached the design capacity in the previous ten years, in his paper gas-water relative permeability curves were tested through experiments, meanwhile production perform-ance for withdrawal cycle was studied by rate transient analysis, and acquired pseudo-permeability of single well as a result.With the combination of relative pseudo-permeability and gas-water relative permeability curve, pseudo-gas-saturation of single well′s drainage area was obtained.Furthermore, the reliability of the method was demon-strated when studying water gas ratio of production data. |

| Keywords: | gas storage reservoir efficiency relative permeability gas saturation rate transient analysis |
