| 摘 要： | 关于气举井的稳定生产，前人已经建立了一些稳定准则，但国内油田收集的油井数据表明，当气举凡尔工作在临界流态时，Alhanati稳定准则不能准确预测气举井生产是否稳定。文中建立了一个新的气举井稳定准则。该准则将摩阻因素考虑进油管压力梯度的计算过程中去，形成了包含描述气举凡尔特征的Kvt和Kvc系数的新稳定准则。油田数据证实新的稳定准则在预测气举井稳定性方面更准确。

| Abstract: | Several scholars have establised stability criterion for the stability production of gas lift wells. But the data of oilfield proved that the Alhanati stability criterion can't predict the production status of gas lift wells correctly when the gas lift valve is working under critical flow condition. A new stability criterion is established in this paper.It considers the friction factor during calculating the pressure gradient of oil tube. At last we get a new equation of Kvt and Kvc which are used to describe the characteristic of the gas lift valve. The data of oilfield prove that the new stability criterion can predict the production status of gas lift wells properly. |
