摘要
研究了在试井中应用微分方程反演理论的可能性。常规的试井分析方法测定井底压力变化，反求油层各种参数，但无法确定其参数的空间分布。应用微伏法对二维渗流力学方程进行反演，提出了利用试井资料确定孔隙度、渗透率随空间变化的方祛，目的是把微分方程反演理论引入试井分析中，提供一种试井分析方法。方程反演理论可望在试井分析中广泛应用。
Inversion of differential equation is applied in many areas of science. This paper discusses the possibility of applying theinversion of differential equation in well test analysis. Although the common method of well test analysis can determineparameters in oil layer, but cannot determine their distribution in space. This papers gives the way by which the spatialdistributions of porosity and permeability are inverted by using well test data and on the basis of 2D differential equation of oiland gas flowing through porous. The author writes this paper with an aim at introducing the theory of inversion into well testanalysis and providing a method for well test analysis, It hopes that the theory of inversion will be applied widely in the areaof well test analysis in the future.
