摘要
通过分析各个评价指标的关系，利用逻辑分析、灰关联度分析及矿场统计分析等方法，最终确定出包括水驱储量控制程度、水驱储量动用程度、年注采比、地层能量保持水平、自然递减率、综合递减率、含水上升率、剩余可采储量采油速度（储采比）、水驱状况（含水与采出程度）、油水井综合生产时率、措施有效率和吨油操作成本等12个开发效果评价指标并制定了其标准，利用层次分析法给出了这些指标的权重，进而基于模糊综合评判方法建立了水驱油田特高含水期开发效果评价体系，经实践证明了该体系的准确性和有效性，从而使水驱油田特高含水期开发效果评价向方法科学化、程序规范化的方向发展，为老油田的调整提供科学的决策依据。
Based on correlation analysis of evaluation indexes, this paper establishes 12 evaluation indexes of development effect and relevant criterions by using methods of logical analysis, grey association degree and field statistics. The above-mentioned indexes include reserves control degree and reserves producing degree of water flooded reservoir, annual injection-production ratio, formation energy maintaining level, natural decline rate, comprehensive decline rate, water cut increase rate, production rate of remaining recoverable reserves （R/P ratio）, water flooding condition （water cut and degree of reserves recovery） , comprehensive productivity of producers and injectors, stimulation effectiveness rate and operation cost of per ton of oil. Weight of the indexes is also established by analytical hierarchy process. An evaluation system of development effect in ultra-high water cut stage of water flooded oilfield is presented in this paper based on fuzzy comprehensive evaluation theory, of which accuracy and validity have been confirmed by field cases. This system may make evaluation of oilfield development effect towards scientific and standardized way and provide a scientific decision-making reference for adjustment of mature fields.
