摘要:

针对外边界定压的双孔介质复合储层模型,研究了两种内边界条件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;此研究,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应用价值。

关键词: 双孔复合储层, 定压外边界, 压力分布, Laplace空间解

Abstract:

In this paper the dimensionless pressure distribution and solutions of variable flowing rate in Laplace space under two inner boundary conditions have been researched in double porosity composite and constant pressure at outer boundary reservoir model, the research improves well test analysis t a wpl vlue to the development of corresponding well test analysis software.

Key words: double porosity reservoir, constant pressure at outer boundary reservoir, pressure distribution, solution of Laplace space
