| 摘 要： | 本文建立了单一介质、双重介质中由两个渗透层被一个致密低渗透层隔开的多层油藏渗流的数学模型,并求得了无穷大地层的精确解和长时渐近解。利用这个解可以在双重介质层状油藏的单井、多井试井中解释压力恢复曲线、垂向干扰试井和垂向脉冲试井。

| Abstract: | Two mathematical models are developed in this paper that describe fluid flow and pressure behavior in a porous medium reservoir and double porous media reservoir consisting of two permeable zones separated by a zone of low permeability, or a "tight zone".Their solutions are obtained which are the exact solutions and the long time asymptotic solutions in infinite formation.The solutions are used to design and to interpret buildup curves,vertical interference tests and vertical pules tests of oil field in a single well or multiple wells for the porous medium and the double porous media. |
