摘　　要：在Raghavan等人的工作基础上 ,导出多层油藏合采条件下的压力动态描述通用的数学模型 ,该模型具有一系列的优点 :①任意井类型和外边界可以组合到各个单层 ;②各层物性、介质类型可以不同 ;③直接利用单层系统的解析解式组合多层系统 ;④压力响应计算方法直接简单。并进一步建立不同初始压力条件下的多层油藏压力响应的变流量迭加方法 ,使多层系统的不稳态压力分析方法更为实用化。Based on many researchers'work such as Raghavan,a general mathematics model for transient pressure of multilayered reservoir has been educed.The model has a series of excellences:①Discretional type of well and outer boundary may be combined every one layer;②Physical property and medium's type can differ each other;③Straightly making use of analytical formula of single layer system combine that of multilayered system;④Calculating method of pressure response is direct and simple;And go step further to establish variety rate convolution method of multilayered reservoir with differently initial pressure.This makes transient pressure analysis of multi-layered system more practical.
