| 摘 要： | 针对长庆低渗透气藏进行修正等时试井过程中出现试采瞬时测试产量大于绝对无阻流量的异常现象，在明确气井瞬时测试产量与其绝对无阻流量概念的基础上，通过对气井绝对无阻流量获得过程及气井绝对无阻流量计算结果影响因素的分析，在理论上证实了气井瞬时测试产量大于其绝对无阻流量的可能性，从而解释了现场测试过程中出现的特殊现象。

| Abstract: | In this paper, in the process of modified isochronal test, abnormal phenomenon that transient test production is greater than absolute unresisting flow rate during producing test in low permeability reservoir Changqing oilfield. Pointed at this phenomenon and based on definitive conceptions-transient test flow rate and absolute unresisting flow rate in gas well, together with the study on influence factors analysis of calculating absolute unresisting flow rate, the possibility which transient test production will greater than absolute unresisting flow rate is confirmed. The possible special phenomenon on the local test process can be interpreted accurately. |
