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,在实际编制相应的应用软件的过程中体现了极大的优越性和实用性。

Abstract: In this paper ,we have systemically presented the Laplacespace solution to bottomhole pressure distribution in complexreservoir with three kinds of outer boundary conditions (infinite uter boundary , closed boundary , constant pressure) and two er 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 simpleand practical general formula provides fundamental theory forwellOt est analysis and has great superiority and practicability in programming applications.

Key words: complex reservoir, boundary conditions, bottomhole pressure, Laplace space solution, general formula
