摘要: 本文用较新的观点,建立了无限大均质地层(考虑井筒储存和表皮效应)中单井系统变流率问题的压力降分布的数学模型,利用Laplace变换法,解出了井底压力变化的精确解析解;并将其无因次化,以便于在实际中用来制作试井分析样板曲线图,并简要地指出了实际应用此精确解的方法。

Abstract: Using a new point of view that assumes the drawdown this paper provides a mathematical model distribution of variable-rate case of a
single-well system in infinite, isotropic and skin effects into consideration The formation, taking wellbore storage model gives an accurate slution to the change in bottom-hole pressure, using Laplace's analytical
transform method,and gives its dimensionless form so as to draw a typical curve for well-test analysis easily in practice.This paper also briefly presents the method of applying the accurate analytical solution.

Key words: Wellbore storage Skin effect Bottom-hole pressu
