摘　　要：针对均质、双孔、复合油藏这3种典型封闭油藏,基于外边界封闭及考虑井筒储存和表皮效应的内边界下诸油藏模型的无因次井底压力动态的Laplace空间解的相似结构理论,利用Matlab工具软件编程,绘制了相应的对比分析图版,形象直观地研讨了诸油藏的类型的判别问题。本文的研究结果对油藏开发方案的制定具有指导意义,且有广泛的应用性。This paper presents a study on the discrimination of three typical confined reservoirs,i.e.homogeneous reservoir,dual porosity reservoir,composite reservoir.Based on the confined outer-boundary and the similar-structure theory of non-dimensional dynamic Laplace Space Solution for these reservoir models,in which the bottom-hole well bore pressure is related to well bore storage and skin affection in inter-boundary,the corresponding comparative analysis charts are drawn out using the programming tool in Matlab.These reservoir models' discrimination is achieved by using these charts.The results obtained from the study are of benefit for making a plan in the development of oil reservoirs.
