摘　　要：断块油藏水驱开发潜力除了受地质、开发及工艺因素影响外,还受复杂边界条件和不规则注采井网等多种因素影响。针对断块油藏水驱开发潜力影响因素多、整体评价困难的问题,在综合分析地质参数指标的基础上,引入油藏形状因子、注采井网度等指标,完善了水驱开发潜力评价体系,同时应用模糊层次分析法建立了综合评价方法。C3K2t13实例分析结果表明:建立的模糊层次分析评价方法能够较准确地反映油藏水驱开发潜力大小,具有较好的适应性和实用性。The developing potential of waterflooding fault-block reservoir is not only affected by the factors of geology,development and technology,but also complex boundary condition,irregular well pattern of injection-production,and other factors.In order to solve the difficulty in overall assessment affected by many factors,based on the comprehensive analysis of geological parameters,introducing the indexes such as the factor of reservoir shape and the degree of injection-production well pattern,etc.the evaluation system for water-drive development potential was improved.Meanwhile,a comprehensive evaluation method was built by fuzzy hierarchy analysis.The case study of C3K2t1^3 indicated that the evaluation method can exactly reveal the water-drive development potential,which has better adaptability and practicality.
