| 摘 要： | 针对双孔介质油藏，建立了考虑井筒储集和表皮效应和三种外边界（无穷大、定压、封闭）条件下的试井分析模型；利用Laplace变换，在Laplace空间中得到了储层压力和井底压力分布的精确解；经全面和深入的分析，发现了描述该类油藏在三种外边界条件下的渗流特征的解式之间具有的相似结构，并作了进一步的讨论。这项研究，极大地方便了试井分析软件的编制，对油气藏渗流规律的理论研究具有深远的意义。

| Abstract: | This paper proposes mathematic model for well test analysis of perfectly describing the dual porosity reservoir with the bottom-hole storage and the skin effects and the three kinds of external boundary conditions (infinite boundary, constant pressure outer boundary and closed boundary). By using the Laplace transform method, the solution of the dimensionless pressure and dimensionless bottom-hole pressure in Laplace space is got. It is discovered the similar structure of the solution of seepage flow characteristics in the three kinds of outer boundary conditions passing through deeply analyses. Furthermore, more discussion is taken. The research is convenient to design well test analysis program, and it is also a deep development of flow theory of fluids in porous media. |
