摘　　要：针对外边界定压的均质储层模型,研究了在控制井底流动压力状态下考虑井筒储存和表皮效应的油气井产率的变化规律。对于相应的数学模型,求得了油气井产率与井底流动压力间关系的Laplace空间解,利用数值反演结果,分析了井筒储存系数和表皮因子对产率的影响。实例表明,该方法可以很好地进行试井分析工作,对油气井产率的预测和指导油气井数值模拟都具有实际意义。Taking wellbore storage and skin effect into account, this paper studied the flow distribution in homogenous reservoir model with constant pressure outer boundary under the condition of controlled bottom pressure. A Laplace space solution was derived for the relationship between well production and bottom flowing pressure. The effect of wellbore storage and skin effect on production was analyzed with numerical simulatioa The method was tested on real data.
