摘　　要：低渗透油田必须早注水,以保持较高的地层压力,防止油层孔隙度和渗透率大幅度下降,保持良好的渗流条件。对比同时或滞后注水,超前注水的区块单井产能明显提高;井组注入能力及井间压力也有一定程度的提高。一般来说,在超前3-6个月注水效果较好,推荐超前6个月。For the reason of holding higher level formation pressure,preventing great fall in porosity and permeability,maintaining better condition of filtering flow,we should execute advance water injection in low permeability reservoir.In contrast with Simultaneous water injection or delaying water injection,we get the higher individual well producing rate of the formation advance water injected,and the higher well group injection capacity and interwell pressure.Usually,the effect of advance water injection is greater if we inject water 3-6 month before the formation put into production,we propose 6 month as the advance time.
