| 摘 要： | 针对外边界定压的双孔介质复合储层物理模型,用数学方法研究了两种内边界条件(是否考虑井筒储存和表皮效应)下的变(常)流率问题的无因次井底压力的Laplace空间解,在深入剖析了解的结构和相互联系的基础上,找出了它与常见的复合、双孔、均质储层井底压力间的相互关系,并简要地引导了相应的应用.此项研究,无疑是对试井分析理论的一种完善,对相应的试井分析软件的研制具有深远的应用价值,对油藏工程中的数值模拟方法也具有指导意义.

| Abstract: | In this paper the bottom dimensionless pressure solutions of variable rate in Laplace space under two inner boundary conditions are researched in double porosity composite reservoir with constant pressure outer boundary physical model. This paper analyzes the structure of solutions, and relations among the bottom pressure in composite reservoir, double porosity reservoir and homogeneous reservoir. It also introduces how to make use of the pressure solutions. No doubt, the research makes well test analysis theory perfect and has wide application value; and it has instructive significance for numerical reservoir simulation. |
