油嘴动态关系式,对于预测油井产能是一个很有用的工具。假若把油嘴看作一个节流式流量计,那么,在理论上便可建立起对于生产井的单相流动和两相流动的油嘴动态关系式,在本文中,对于由文献1、2提供的经验关系式Q_0=C_1dlgd和Q_0=1.045~(-d)C_2d~2提出了质疑,并进行了讨论。
The dynamic behavior of the nozzle is a useful tool for predicting well productivity. If the choke is regarded as a choke meter, then the theoretical relationship between the single-phase flow and the two-phase flow in the production well can be established. In this paper, Empirical relationship Q_0 = C_1dlgd and Q_0 = 1.045 ~ (-d) C_2d ~ 2 raised the question and discussed.
