摘要: 基于产水气井稳定产能方程,推导了适合产水气井的一点法预测公式。与常规气井相比,产水气井一点法产能预测公式中的经验参数还与气井产水量相关,且随着水气质量比RWG增大,经验参数逐渐减小,预测的无阻流量也逐渐减小。在实例中,建立了某有水气藏的预测公式,由检验分析表明,该公式计算结果可靠性高,方法是切实可行的。

Abstract: Based on the steady deliverability equation for water-producing gas wells, a single point deliverability forecasting formula for them is derived. The result shows that compared with conventional gas wells, the empirical parameter in the formula for water-producing gas wells is also related to the water production from gas well, and with the increasing of water/gas mass ratio (RWG), the empirical parameter will decrease gradually and the predicted open flow potential decreases too. In the case study, the single point deliverability forecasting formula for water-producing gas reservoir is established. It is shown that the formula is more reliable and practicable.
