【摘要】 缝洞型碳酸盐岩油藏储集空间类型多样,组合形式复杂,不同的储集体组合形式对注水开发的影响差别很大。复杂的储集体组合可以看作是基本储集体组合的重复,基本的储集体组合主要有洞-洞、缝孔-洞、缝孔-缝孔三种。在对单井钻遇储集体、井间储集体识别以及前人对井间连通性分析的基础上研究不同储集体组合对注水开发效果的影响。虽然不同的储集体组合对注水效果有不同的影响,但总体表现为孔渗性差的储集体注水,孔渗性好的储集体采油效果较好。最后以塔河油田6～7区实际的储集体组合举例分析了不同储集体组合对注水开发效果的影响。更多还原

【Abstract】 Various accumulation capacities exist in fractured-cave carbonate reservoir and the combination of reservoir is complex,which have great different influence on water injection development. There are mainly three basic reservoir combinations: cave-cave combination、fracture&pore-cave combination and fracture&porefracture&pore combination. The actual more complex reservoir combinations can be considered as the duplication of these three basic types. On the basis of reservoir recognition around and between wells,together with the analysis of connectivity between wells,the impact of different reservoir combination to water injection development are slndied.Although different reservoir combinations have different impact on water injection development,on the whole,water injection in reservoir with poor porosity and permeability and production in reservoir with good porosity and permeability has good effect. Finally,the impact of reservoir combination to water injection development effect in 6 ～ 7block Tahe oilfield are stndied.更多还原
