摘　　要：油水井稳油控水能力的准确分类评价是制定油藏合理工作制度和调整措施的重要依据。通过深入分析实际水驱油藏开发效果影响因素,综合考虑采油井的生产能力、开发潜力和注水井的吸水能力、驱替效率等,筛选并建立了油水井稳油控水能力评价指标体系;利用模糊C均值聚类算法,定量系统化处理不同类型指标、不同变化范围对综合稳油控水能力分类评价结果的影响,进而形成了水驱油藏油水井稳油控水能力分类评价方法。渤海PL油田某区块的实例计算表明,利用本文方法可以快速、准确地确定出不同阶段油水井稳油控水能力分类结果,进而明确油藏不同区域存在的主要开发问题,为下一步合理开发调整提供依据。The accurate classification and evaluation of the capability of stabilizing production and control-ling water of producing and injection wells are important for determining working systems and adjustment measures. Based on the analysis of influence factors of water flooding reservoirs and the consideration of well productivity, development potential and well injectivity, an evaluation system of the capability of sta-bilizing production and controlling water for producing and injection wells is selected and established. Based on the quantitative effect analysis of different indices and the corresponding variation ranges on the classification and evaluation system with fuzzy C-mean clustering algorism, the method of classification and evaluation of the capability of stabilizing production and controlling water of production and injection wells is established. The application in PL oilfield in the Bohai sea shows that the method can quickly and accu-rately determine the classification and evaluation results in different development stages, and can identify ＂the key development problems in different parts of the reservoir, providing basis for further adjustment.
