| 摘 要： | 基于Xu & Lee的凝析气井试井分析数学模型,采用Hegeman提出的井筒相再分布压力的误差函数表达式,建立考虑变井筒存储的三重介质凝析气井试井解释数学模型.通过Laplace变换和Stehfest数值反演进行求解,绘制其压力及压力导数曲线,并分析研究井筒相再分布压力系数等对压力和压力导数动态的影响.

| Abstract: | In a condensate gas reservoir welhest model of Xu & Lee, error function express of wellbore phase redistribution is adopted and a mathematical model of variable wellbore storage in triple porosity condensate gas reservoir is shown. With Laplace transformation and Stehfest inversion, effects of pressure parameters on pressure and differential of pressure are analyzed. Typical pressure curves are given. |
