摘　　要：Fair变筒储存模型已广泛地应用于油气井变井筒储存情况的试井分析,由于实际测试资料里变井筒储存响应的复杂性,以及对有关理论认识不足,使得人们应用起来比较困难。通过系统研究积液气井的Fair变筒储存模型不稳定压力响应特征,得出了Fair模型各种情况下理论曲线变化的规律性认识。Fair's variable well-bore storage model has been widely used in the well test analysis for a gas/oil well in the world.Fair's model is difficult to be applied to analyzing the field well test data because of the complexity of variable well-bore storage effects and the lack of a good knowledge of Fair's model for the interpreters.This paper outline the transient pressure response of Fair's model for a gas well with liquid yield effects and present the character of the type curves of Fair's model under the different model conditions.
