摘要: 针对溶洞为主的溶洞-裂缝型碳酸盐岩油藏特征,在分析储层特征和缝洞组合模式的基础上,初步探讨了缝和洞的流动机理、储集空间连通关系,最后讨论了不同开发阶段不同缝洞组合模式下,孔洞的不同作用。Abstract: In accordance with the characteristics of fractured- vuggy carbonate reservoir,based on the analysis of reser- voir features and the fracture-cave combination pattern, the flow mechanism and connectivity among reservoir space has been first discussed in this paper.Under differ- ent combination patterns in different development phases, the action of cavities has been finally discussed.
