研究气井积液的成因及条件对于防止气井积液十分重要.目前国内普遍采用Min LI模型或Turner模型应用于气井的积液判断,并发现使用Turner模型计算出来的值偏大,而使用Min LI模型获得的数值又偏小.从以上连续携液模型的原理出发,阐述了其应用的适用条件并对方法进行了综合比较,研究发现目前这些模型均认为当液滴静止时所需气流速度即为判断气井积液的临界流速,这与实际情况明显不符,故提出新的模型,最后引入现场实例进行论证.

Research the causes and conditions of gas well load-up is very important to prevent gas well load-up. Produced liquid phase with natural gas from a reservior occur, which will accumulate in the bottom of the well over time when the transporting energy is not high enough. Thus the liquid accumulation leads to additional hydrostatic pressure on the reservoir, resulting in a continued reduction of available transportation energy and affecting the production capacity. So it is key to calculate gas well load-up accurately, which is important to adopt feasible means to work out problems. Currently Min LI model and Turner model are applied to predict the gas well load-up for domestic, and it has been proved that the first model calculated out bigger values, the later got smaller. In this paper, the ways from the continuous fluid model portability principle, evaluating its application conditions and making comprehensive comparison. The study shows current models hold that it is gas well critical rate of flow when liquid droplet is motionless, however it is not agree with actual conditions, so new model is proposed, the last example to demonstrate the introduction of the scene.
