摘　　要：应用油藏工程与数值模拟相结合的方法,设计了扶余油层超前注水方案.地层压力保持水平、累计注水量、超前注水强度、超前注水时机的研究表明：超前注水能够建立有效的压力驱替系统,提高地层压力,减小应力敏感损害,改善油田开发效果;扶余油层合理的压力保持水平为120％、超前注水时间约7个月.研究成果为低渗透油田开发提供了技术支持.With the help of the integrated method between oil reservoir engineering and numerical simulation, the leading water injection program for Fuyu oil layers is designed. The researches on the formation pressure maintained level, accumulative water injection rate, leading water injection intensity and its opportunity show that the leading injection can establish the effective pressure displacing system, thus the formation pressure can be increased, the pressure sensitivity damage can be reduced and finally the oilfield development effects can be improved; the rational pressure of Fuyu oil layers is maintained by 120% , and the leading injection lasts for about seven months. The study achievements have provided the technical supports for the development of the low-permeability oilfield.
