摘　　要：基于低渗透油田存在启动压力梯度、油水井间难以建立起有效的压力驱动压差,提出采用超前注水的开发模式。通过对新立油田119区块的数值模拟,得出了该区块超前注水时机为5个月,压力保持水平为137%,并分析了超前注水压力分布特征和增产机理。该研究成果可以更好地指导新119区块的有效开发,也为其他低渗透油田开展超前注水技术提供技术依据。In consideration of the problems of starting pressure,effective driving pressure difference being hard to be established between oil and water wells in low permeability oilfields,it was proposed that advance water injection was used.Numerical simulation was conducted in Block 119 of Xinli Oilfield,the period of advance water injection was 5 months in the block,pressure holding level was 137%.The pressure distributive characteristics of the injection and stimulation mechanism were analyzed.The result can be used to effectively guide the development in Block 119 and provide technical basis for advance water injection in other low permeability oilfields.
