气井及凝析气井连续携液模型的统一

气井及凝析气井积液是气田开发过程中的一个严重问题，目前关于气井连续携液模型种类繁多，且缺少富含凝析水的定向凝析气井临界携液流量模型。本文在目前广泛采用的Li Min携液模型基础上，推导出了富含凝析水的定向凝析气井临界携液流量模型，并将现有的气井和富含凝析水的凝析气井临界携液流量模型进行了统一。研究认为，在计算富含凝析水凝析气井的临界携液流量时，气井携水比携油困难，所以只需达到最小携水产气量即可，无需考虑油、气、水三相复杂相态变化。同时发现，由于定向气井存在着管斜角，使得定向井的临界携液流量要比直井大得多。气井及凝析气井连续携液模型的统一，极大的方便了现场工人及相关科研工作者的计算。

A Unified Mode for Continuous Removal of Liquids from Gas Well and Condensate Gas Well

Liquid loading of gas well and gas condensate well is a serious problem in the process of gas field development. Many formulas related to the determination of critical rate for continuous removal of liquids from gas well have been proposed, but there is no one for directional gas condensate well enriched condensated water. On the basis of Min LI model of continuous carrying fluid model which has been widely used, we deduce continuous carrying fluid mode of directional gas condensate well enriched condensated water, and unified the continuous carrying fluid mode of existing gas wells, and gas condensate wells with high condensate water. Studies show that it is no need to consider the oil, gas and water complex phase change for safety reasons, when we calculate critical carrying fluid rate of gas condensate well enriched condensated water. Simultaneously, we found that, due to the tube angle presence of directional wells, it makes the critical carrying liquid flow rate much greater than the vertical wells'. We unified the mode for continuous removal of liquids from gas well and condensate gas well, which greatly facilitate the on-site workers and the associated scientists.
