摘　　要：根据人们对压裂气井不稳定渗流机理的认识,应用压裂气井有限导流垂直裂缝不稳定渗流模型,结合Cullender-Smith管流计算方法,提出一种预测压裂气井稳产时间的简便方法,编制出特低渗透气藏压裂井稳产时间预测软件。实际应用表明,该软件使用方便,预测结果与数值模拟预测结果基本一致,对气井合理配产有一定的参考价值。Based on the previous studies on transient percolation mechanism for fractured gas wells,applying the transient flow model of gas wells with a finite conductivity vertical fracture and combining with conduit flow calculation method proposed by Cullender and Smith,we put forward a convenient method of predicting the time when stable production begins for fractured gas well,and made software of corresponding prediction for extremely low-permeability gas reservoir.Application of this software has shown that the software is very convenient to use,that its results are nearly the same with numerical simulation and that it provides a good reference for gas well proration reasonably.
