| 摘 要： | 基于多孔介质流体质点渗流规律，考虑高产气井近井地带非达西效应，对具有近似直线供给边界的边水气藏见水时间的预测方法进行研究。考虑气体非达西效应、气水流度比、原始束缚水饱和度、残余气饱和度、气井距边水的距离等影响因素，并通过数学推导，得到高产气井边水气藏水舌突破时间的计算公式。应用表明，该公式考虑了气体非达西效应，与未考虑气体非达西效应的气井见水时间预测方法相比，预测时间更符合实际情况，对现场生产管理具有重要现实指导意义。

| Abstract: | The study on predicting water breakthrough time in gas wells with the approximate straight line edge water supply is based on flow law in porous media, considering non-Darcy effects of near wellbore area in high gas rate wells. Through mathematical derivation, the formula of water breakthrough time on high gas rate wells with edge water is derived, considering non-Darcy effects, gas/water mobility ratio, initial irreducible water saturation, residual gas saturation, and the distance from gas well to edge water and so on. Application shows that the water breakthrough time prediction is more realistic taking into account non-Darcy effects than without, which has important practical significance for on-site production management. |
