摘　　要：生产效率是反映水驱油藏生产能力及驱替效果的重要指标,基于生产效率分析和评价不同注采单元的控水稳油能力及影响因素,是油藏制定适宜调整措施的重要依据。通过系统分析油水井的生产能力、产油效率、驱替效果等影响开发效果的各方面指标,筛选并建立油水井生产效率评价指标体系;利用数学统计分析方法,系统化处理不同指标对生产效率分级评价结果的影响,建立油藏生产效率分级评价方法。结合油田开发实例,在油水井生产效率分级评价的基础上,明确了不同注采单元的控水稳油能力及生产特点,结合影响生产效率的地质、开发因素综合分析,提出了针对性的开发调整措施,可为此类油田的有效开发奠定基础。Production efficiency is an important index to reflect the production capacity and displacement characteris- tics of water - drivel reservoir. According to the production efficiency, the ability and influencing factors of water control and stabilizing oil production for various injection -production units were analyzed and evaluated, which are an important basis to make appropriate adjustment measures. An evaluation system for production efficiency of oil - water wells was established based on the analysis of the production capacity of oil - water wells, oil production efficiency, displacement char- acteristics, and so on. The influence of different parameters on the classification evaluation of production efficiency was systematically analyzed by using mathematical statistical method. On this basis, the classification evaluation method for reservoir production efficiency was established. Based on the classification evaluation of production efficiency of an oil field ,the ability of water control and stabilizing oil production and production characteristics for various injection - production units was obtained. Combined with the geological and developmental factors influencing production efficiency, the development adjustment measures are proposed.
