Abstract

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
