摘　　要：在凝析气井生产中,井筒会出现积液,导致试井资料出现异常,用以前的试井理论图版无法进行拟合解释。从数学模型表达方法上看,带积液的气井试井模型与井筒相态重新分布的气井试井模型类似,都是在井底增加了一个附加压力。从此入手,建立了带积液的凝析气井试井分析模型,加以求解,画出了其特征曲线,并对其各个阶段的流动特征进行了分析。实例分析证明,利用该试井分析模型和相应的理论图版进行凝析气藏解释,可得到较好效果。In producing process of gas-condensate well, reservoir has accumulated liquid is often appeared in well-bore which results in abnormal data of well testing and matching interpretation using the conventional theoretical type-curves can not been conducted. In expression of mathematical model, the model of well test of gas reservoir when well bore has accumulated liquid is similar with the model of well test of gas reservoir of well bore's phase state redistribution, both adding an additional pressure of well bore. Therefore, by analyzing this feature, the well testing analysis model of gas-condensate reservoir with accumulated liquid at well-bore is set up, solution to it is derived and the typical curves and flowing feature at every intervals are drawn and analyzed. Applied example proves that by using of this well testing analysis model and its corresponding theoretical chart is used to gas-condensate reservoir, a proper result can be reached.
