摘要
针对油气藏中的复合双渗封闭储层模型,研究了两种内边界条件下的变流率问题的无因次压力分布的Laplace空间解,在深入剖析了解的结构和相互联系的基础上,找出了它与常见的复合、双渗、均质储层压力分布间的相互关系。进一步完善了试井分析理论,对相应试井分析软件的研制具有较高的应用价值,对油藏工程中的数值模拟方法也具有指导意义。
Aimed at the sealed reservoir model with composite dual permeability, the Laplace space solution of di-mensionless pressure distribution of variable flow rate under the condition of two types of interior boundary is studied , and on the basis of deeply probing the structure and the relationship of the solution, the relationship between the solution and composite dual permeability and homogeneous reservoir pressure distribution is figured out. The well test analysis theory is further improved , and the method is very valuable to the development of the corresponding well test software, meanwhile, it is also meaningful to numerical simulation of reservoir engineering.
