The Exact Analytical Solutions to the New Model of Reservoir Filtration Problem

摘要: 本文在考虑到井筒储集和表皮效应情况下,利用双重介质渗流方程组建立了油藏渗流问题的新模型,并通过各种极限形式得到了外边界为无限大,有界封闭,有界定压三种情况下二类常见油藏(裂缝性油藏,均质油藏)内压力分布的精确解析表达式.

Abstract: In this paper,under considering wellbore storage and skin,the new model of the reservoir filtration problem by taking into account the effect of wellbore storage and skin and by making use of the coupled equations of doubled porous media filtration,and through various forms of limits.we have obtained the exact analytical solutions of pressure distribution on two kinds of general reservoirs the three common reservoirs(fissure reservoir,homogeneous reservoir) and under three conditions,i.e.,infinite boundary,finite sealed boundary and the finite boundary at constant pressures.
