WELL TEST ANALYSIS OF STRONGCOMPRESSIBLE FLUIDS

本文研究了强可压缩液体的不稳定渗流理论,利用拉普拉斯变换方法,获得了井底压降的精确解,并讨论了精确解在渗流早期及无限作用径向流动期的渐近表达式,提出了新的试井分析方法,目前弱可压缩液体的试井分析方法只是本文的特例。

<ABSTRACT>: The theory of unsteady-state flow of strong compressible fluids is discussed in this paper. With Laplace transform method, the accurate solu-tion of bottom hole pressure differential is obtained and the approach expre-ssion of the accurate solution at the early stage of flow and the initial stage of infinity radial flow is discussed, putting forward a new well test analysis method. The method of well test analysis of weak compressible fluids is only a specific case of this paper.
