摘要
针对双孔介质复合封闭储层模型,研究了两种内边界条件(是否考虑井筒储存和表皮效应)下的变流率问题的无因次内、外区储层压力分布的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、均质储层压力分布间的相互关系。此项研究,无疑是对试井分析理论的一种完善,并填补了试井分析理论在此方面的空白和不足,对相应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。
Based on the composite bounded reservoir model with two porous media, the Laplace solution of dimensionless pressure distribution under inner boundary condition (considering the wellbore storage and the skin effect) has been studied, and through analyzing the structures and interrelations of Laplace solution, the correlations with usual composite, two porous media and homogeneous reservoir pressure distribution have been found. This research is a perfection and supplement to the well test analysis theory, it has the application value for well test analysis software development, also has help for the research on numerical simulation method in reservoir engineering.
