为有效控制水驱油藏窜流现象,提高注水利用率,需要确定油藏存在窜流的低效循环场区域.基于水驱开发油藏的特点及影响因素,建立包括油藏静态、动态参数的注采有效性评价指标体系；应用模糊综合评判理论,提出注采有效性评价指标量化分级标准、影响因素分级权重标准和注采有效性分级标准；结合油田实践,进一步建立油藏注采有效性计算评价方法和步骤.根据建立的综合评判方法,分析评价了江苏油田某油藏水驱开发的注采有效性,研究结果为油藏实施综合治理提供了技术支持.%It is necessary to define the region of low efficiency circulation where water channeling occurs in a reservoir so as to improve water injection efficiency. An evaluation index system for the effectiveness of injection and production is established based on the characteristics and influential factors of waterflooding reservoirs. Using fuzzy synthetic evaluation theory, this paper proposes quantitative grading standard, influential factor grading weight standard, and injection - production effectiveness grading standard. The calculation and evaluation method of reservoir injection - production effectiveness is established coupled with oilfield practice. A watetflooding reservoir in Jiangsu Oilfield has been evaluated for injection - production effectiveness by using the established method, and the evaluation result has provided technical support for implementation of comprehensive reservoir management.
