| 摘 要： | 由于低渗透气藏的特殊性,传统的压降法、弹性二相法等动态储量的计算方法在低渗透气藏中不适用,或者适用条件苛刻,需要经过复杂的修正,应用复杂.提出了一种计算低渗透气藏动态储量的新方法--产量不稳定法,该方法基于Blasingame等人的物质平衡方程与拟稳态方程相结合的理论,利用单井生产历史数据(产量和油、套压),计算动态储量.给出了低渗透气井的应用实例,综合分析表明该方法比传统方法更适合低渗透气藏的动态储量评估. |

| Abstract: | Because of the particularity of low-permeability gas reservoir,the traditional methods to calculate the dynamic reserves,such as pressure drawdown method and elastic 2-phase method,don't fit to the low-permeability gas reservoir properly,or need harsh requirements,Which is hard to use.This article presents a new method to calculate dynamic reserves of low-permeability gas reservoir,which is so-called rate transient method.Basing on the combination of material balance equation and pseudo-steady flow equation... |
| Keywords: | low-permeability gas reservoir material balance pressure drawdown method pressure drawdown method elastic 2-phase method rate transient method |
