摘要
系统地给出了复合油藏中 ,三种外边界条件 (无穷大、封闭、定压 )及两种内边界条件 (即在井底是否考虑井筒储存和表皮效应 )下井底压力分布的Laplace空间解 ,全面分析了它们之间的相互联系 ,并得到了一个通式 ,给复合油藏试井分析提供了坚实的理论基础 。
In this paper,we have systemically presented the Laplace space solution to bottomhole pressure distribution in complex reservoir with three kinds of outer boundary conditions (infinite outer boundary, closed boundary, constant pressure) and two inner boundary conditions(wellbore storage and skin effects), and the relationship between the solutions are also analyzed completely, and then a general formula is derived. This simple and practical general formula provides fundamental theory for well-test analysis and has great superiority and practicability in programming applications.
