摘　　要：给出了双渗油藏中 ,在三种外边界条件 (无穷大、封闭和定压 )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 )下的压力分布的Laplace空间解 ,分析了它们之间的相互联系 ,并给出了一个通式。这给双渗油藏的试井分析提供了坚实的理论基础 ,在实际编制应用软件的过程中体现了极大的优越性和实用性。Laplace space solution of pressure distribution on conditions of three outer boundaries (unlimited,limited and constant pressure) and two inner boundaries (considering well storage and face factor) is presented systemically in dual percolation reservoir and their inter relationships have been analyzed fully and a general equation is given.That provides a theoretical basis for well testing analysis to dual percolation reservoir and shows a great priority and practicability of applied soft ware compiled actually.
