| 摘 要： | 榆林气田山2气藏部分井产水量大,已经严重影响了气井产量.从气藏构造、沉积环境、储层物性和单井产水动态数据等方面研究了气藏产水机理与特征,并分析了气藏产水的影响因素及其影响程度.结果表明:气藏构造对气水分布影响显著,西南构造下倾方向成为富水区;沉积特征使山2气藏的非均质性严重,对气水分布的影响也非常明显,位于分流河道砂体的气井产水少,位于分流河道砂体边缘的气井产水较多;储层物性的差异越大,造成气水的分异作用越突出,致密储层部位气井含水饱和度相对较高,产出液气比较高. |

| Abstract: | Some wells of Shan2 gas reservoir in Yulin Gasfield produces a lot of water,which affect the gas production of gas wells. Mechanism and character of waler production in the gas reservoir are researched from the aspects of structure of reservoir,depositional environment physical property of reservoir and dynamic water production data of single well. The influencing factors and degree are also analyzed. The results show that the structure of gas reservoir is an important influence factor of gas-water distribu... |
| Keywords: | water production character structure of gas reservoir depositional character physical property of reservoir water-rich area Yulin Gasfield |
