| 摘 要： | 产水气井在开发过程中,随着压力的降低,析出的凝析水与地层水会逐渐向井底聚集,一方面引起气井生产过程中水气比的上升,同时还会破坏地下油气渗流环境,影响气井产量.文章利用气体非达西稳定渗流基本原理,同时结合气井生产水气比与气水相渗曲线,通过等效表皮系数,对产能方程进行修正,最终获得预测产水气井(藏)产能预测的方法.实例计算...

| Abstract: | In the exploitation process of water - producing gas well,condensation & formation water will gradually move to the well bottom with the pressure decay.The WGR will be raised during production,at the same time underground flow condition will be destroyed,eventually influence well production. In this paper we use gas's non - Darcy flow theory, combine with WGR & gas - water relative permeability curve,via equivalent skin factor to correct deliverability equation & IPR curve.Finally get the forecasting method... |
