| 摘 要： | 非达西效应在压裂气井生产过程中必然存在 ,引入与气水流动速度相关的非达西流动校正系数 ,建立了一套压裂井气水两相数值模拟模型 ,考虑了地层非均质性以及裂缝导流能力随位置和时间变化 ,并研制了预测压裂气井生产动态的数值模拟软件。应用研制的软件对影响压裂气井产能的地层及裂缝参数进行了大量的实例对比计算 ,模拟结果对于气井压裂方案优化设计具有重要的指导意义

| Abstract: | Non-Darcy flow exists in fracturing gas-wells.Through introducing non-Darcy flow coefficient which is relative to the flowing velocity of gas or water,a set of numerical model with gas and water was developed which considers formation heterogeneity and the variation of fracture conductivity with fracture site and time.The numerical simulation software has been developed for predicting productivity of fracturing gas-well.A great deal of calculation is done by changing the input parameters of formation and fracture.The result has important instructive meaning for optimization design of fracturing gas-well. |

| Keywords: | fracturing fracturing of gas-well non-Darcy flow numerical simulation |
