摘 要: | 苏X井地层产水后,二项式系数A、B均增大,无阻流量降低.若发生水锥,则变化程度更大.针对苏X井地层产水后的动态特征,提出采用复合模型来研究地层产水后的二项式产能方程,进而计算当前无阻流量.推导出了产水气井的二项式产能方程和无阻流量计算公式,求出了苏X井地层产水后的产能方程和无阻流量.该研究成果为确定产水气井的产能方程和无阻流量提供了新方法.

Abstract: | Compared with no water-producing,after gas well producing water,A,B coefficients of its binomial deliverability equation will be greater and its open-flow capacity will be less.If water cone occurs,the change of A,B coefficients and the open-flow capacity will be more.According to the dynamic characteristics of Su-X producing-water gas well,it is proposed that a compound model is used for describing the binomial deliverability equation of the well,and then the current open-flow capacity is calculated.The binomial deliverability equation and the open-flow capacity formula of producing-water gas wells are derived,and the deliverability equation and the open-flow capacity of Su-X gas well are calculated.The study provides a new way for determining the deliverability equation and the open-flow capacity of water-producing gas wells. |
