摘　　要：榆林气田主气层山_2气藏是典型的岩性气藏,储集砂体横向变化剧烈,非均质性强,具有低孔低渗特征。为了使气藏得到有效开发,科学合理地管理气田,有必要加深对榆林气田储层特征的认识。为此,利用气藏动态描述的方法,分别从储层性质、气藏类型、气井酸化压裂效果和邻井干扰等几个方面,对榆林气田42口不稳定试井资料进行系统地追踪分析,进一步研究气藏储层特征,了解气藏的边界、气井污染等,并对榆林气田上古砂岩气藏进行了综合评价,为今后的储层评价与预测提供依据。The main gas reservoir in Yulin gas field is a typical lethargically gas reservoir. The reservoir sand body changes sharp, non-homogeneous strong, with the characteristics of low porosity and permeability. In order to exploit gas reservoir effective, scientific and rational management of gas field, we need to deepen understanding of reservoir characteristics of the Yulin gas field. Our analysis depend on the method described in gas reservoir The analysis carries on from the reservoir property, gas reservoir type, gas acid fracturing effects and adjacent wells interfere and so on. The systematic follow-up analysis of instability in the Yulin Gas Field Test data of 42 wells. We have studied the gas reservoir characteristics, the boundaries of gas reservoir, gas well pollution. We undertook a comprehensive evaluation to the ancient sandstone gas reservoir in Yulin gas field, Which provides the basis for evaluation and prediction, for the future.
