摘要(Abstract)：

针对碳酸盐岩断溶体油藏建模中孔隙度、渗透率等参数难以确定的问题,运用岩溶模型演化和油藏开发动态分析相结合的建模方法,利用能量指示曲线、注水指示曲线的动态数据,建立了"2大类5亚类"油藏模型识别图版。依据图版可识别不同储集空间类型的断溶体油藏,并建立相应的油藏模型。通过在单一储集空间缝洞密集群多频次体积酸化恢复扩大泄油体积、多储集空间缝孔联合体远距离酸化建立连通通道、多储集空间缝洞密集群复杂缝酸化提高导流能力等实际应用表明,该识别方法简单有效,应用性强,对指导精准措施、高效注水注气和提升开发效益均有借鉴意义。
In view of the problem difficult to determine the parameters of the porosity and permeability in the modeling of fault-karst carbonate oil reservoirs, the combined modeling between the karstic model evolution and reservoir development dynamic analysis was applied to establish the identifying chart boards of " 2 categories and 5 subcategories" reservoir modeling with the help of the dynamic data of the energy indicating curve and water injection indicating curve. The results show that according to these charts, the fault-karst carbonate oil reservoir with different accumulating spaces can be identified and the corresponding reservoir models were established. The actual following applications in the resolved and enlarged volume by multi-frequency volume acidification in the dense group with the single-accumulating-space fracture and cave, in the built connective channel by the long-distance acidification of the multi-reservoir-space fracture-pore complex and moreover in the enhanced conductivity by the complex fracture acidification of the multi-reservoir-space fracture-cave dense group show that the identifying method is simple, effective, highly applicable and possesses reference significances for guiding the precise measures, high-efficiency water flooding and gas-driving and furthermore improving the development benefits.
