多层气藏中气体流动问题的新模型及其应用

New Model of Gas Flow Problem in Multi-Layered Gas Reservoir and Application

本文针对气井产量与井筒集是变数时,建立了多层气藏内真实气体渗流问题的新模型,求出了三种典型外边界条件下各储层压力分布精确解,作为特例,又得到了均质气藏内压力分布的精确解并给出了在气田开发中的应用.

In this paper, the new model of real gas filtration problem has been presented in multi-layered gas reservoir, when a gas well output and wellbore storage may be variable, and have obtained the exact solutions of pressure distribution forveach reservoir bed under three kinds of typical out-boundary conditions. As a special case, according to the new model have also obtained the exact solutions of pressure distribution in homogeneous reservoir and is given important application in gas reservoir development.
