摘要
针对层间无窜流的多层油藏渗流模型,研究了3种外边界下的交流率问题的储层压力动态分布和井底压力的Laplace空间解。在深入剖析了解结构的基础上,具体分析了各个解的结构,找出它们之间的相互关系,归纳出了一个统一的通式,找出了储层压力分布和井底压力间的相互关系。该研究完善了多层油藏试井分析的理论,对开发相应的应用软件具有指导价值。
The Laplace space solution to dimensionless reservoir pressure and dimensionless bottom pressure of variable flow problem , which takes into consideration the effect of three kinds of outer boundary conditions, is studied by using multi-layered reservoir model. A general formula is concluded through deep analysis to solution structure and internal relation among several solutions. The result in this paper is a good help to application software design, and makes well test analysis theory completed than before as well.
