摘　　要：缝洞型碳酸盐岩油藏储集空间由溶洞、裂缝、溶蚀孔洞组成,溶洞是该类油藏的主要储集空间,也是区别于其他类型油藏的最主要特点。现有的多重介质模拟方法无法准确描述未充填溶洞内流体流动的特征。为此,在多相流模型和有限体积数值解法的基础上,建立了溶洞内多相流体计算模型,实现了溶洞内多相流体流动的描述,并针对缝洞型油藏特点研制了数值模拟软件平台。该软件实现了缝洞型油藏数值模拟的数据管理、方案管理、模拟计算、数据显示等功能。应用实例表明该软件能够实现缝洞型油藏数值模型建立、生产历史拟合、剩余油定量描述、潜力区域分析等工作。The reservoir space of fractured-cave carbonate reservoirs consists of karst caves, fractures and dissolved pores. The karst cave is the main reservoir space of this kind and is also the main characteristic different from other types. Existing multi-media simulation methods can not accurately describe the characteristics of fluid flow in unfilled caves. Based on the multiphase flow model and finite volume numerical method, this paper establishes a multiphase fluid calculation model in karst cave, realizes the description of multiphase fluid flow in karst cave, and develops a software platform for numerical simulation according to the characteristics of fractured-cave reservoirs. The software realizes the data management, scheme management, simulation calculation and data display for numerical simulation of fractured-cave reservoirs. The practical application shows that the software can realize the establishment of numerical model of fractured-cave reservoirs, production history fitting, quantitative description of remaining oil and potential region analysis.
