摘　　要：碳酸盐岩缝洞型油藏与碎屑岩油藏及其它裂缝孔隙型的碳酸盐岩油藏有本质区别,溶洞、裂缝、溶蚀孔隙3种孔隙类型共存,使得传统的碎屑岩油藏建模理论、方法面临挑战。该文提出了以缝洞单元为基础的缝洞型油藏"5步法"建模技术,即建立溶洞分布模型、裂缝离散分布模型、溶洞物性参数模型、裂缝参数模型和缝洞连通体模型。地质模型描述和刻画缝洞体三维形态展布、属性分布,为开发该类油藏提供了理论基础。Carbonate fractured-vuggy reservoirs are basically different from clastic or other fracture-pore reservoirs. Karst caves, fractures and corroded pores coexist in the carbonate fractured-vuggy reservoirs and challenge traditional clastic reservoir modeling theories and methods. A new modeling technique based on fractured-vuggy unit has been proposed. It is featured by ＂5 steps＂ including the establishments of 5 models： cave distribution, fracture discrete distribution, cave petrophysical parameter, fracture parameter as well as fracture and cave con- nection. The model illustrates the 3 D distribution and features of fractured-vuggy reservoirs and provides theoretical basement for reservoir exploration.
