摘要
产水气井的压力恢复特征不同于纯气井。根据径向复合储层模型 ,将产水气井压力恢复曲线的上翘特征解释为气、水流度的变化 ,内区为气体流动 ,外区为水流动 ,代替了传统的边界效应解释 ,结合矿场实例 。
The pressure buildup properties of a water production gas well are different from those of a pure gas well.Inaccordance with radial cmposite reservoir model,the upwarping property on pressure buildup curve of a water production gas well is interpreted as changes of gas and water mobility,inner area in gas flow and outer area is water flow,this new understanding has replaced conventional interpretation of boundary effect,combined with actual field cases,thes paper explains its usability.
