| 摘 要： | 低渗气藏地层压力恢复慢,尤其是低渗气藏开发中后期,这给准确求取目前地层压力带来了困难。通过分析榆林气田X井区长关井井口压力恢复资料,结合垂直管流动理论,提出了一种计算低渗气藏目前地层压力的新方法。通过与物质平衡法和产量不稳定分析法计算结果对比,表明新方法简便易行,计算结果可靠。

| Abstract: | The rate of formation pressure recovery is slow in low permeable gas reservoirs, especially in later period of the exploitation, which makes it difficult to obtain of formation pressure. By analyzing long shut-in pressure recovery data in Yulin Gasfield, this paper presents a new method to calculate formation pressure by combining with the flow characteristics in a vertical tube. Compared with other calculation methods’results , it is proved that this new method is simple and reliable. |
