摘　　要：利用压力叠加的方法求解拉氏空间下考虑观察气井开井生产时的井底无因次压力,通过Stehfest数值反演方法求得井底无因次压力响应曲线,分析了激动气井无因次距离和无因次产量对井底无因次压力响应的影响因素。通过分析发现,考虑观察气井开井时的干扰试井压力响应曲线存在早期、中期、晚期等三个流动阶段。By method of superposition to resolve the dimensionless pressure solution in Laplace domain considering the condition that the observation gas well is open and using the theory of Stehfest to obtain the type curve of dimensionless pressure response in bottom hole, the influence of such factors as dimensionless distance of perturbed well and dimensionless producing rate to dimensionless pressure response in bottom hole is analyzed. According to the type curve of dimensionless pressure response in bottom hole, it is found out that three flow periods which are early period, middle period and late period are existed.
