摘　　要：七里村野猪峁区块是典型的低孔特低渗岩性油藏,注水开发以来含水上升迅速,产量递减快。为了提高水驱开发效果,需要对注水参数进行优化设计。研究发现野猪峁区块最佳注水速度为8m^3/d。Qilichun yezhumao block is a typical low porosity and ultra-low permeability lithologic reservoir.Since the water injection development,the water cut has risen rapidly and the production has declined rapidly.In order to improve the effect of water drive development,it is necessary to optimize the water injection parameters.It is found that the best water injection rate is 8m^3/d.

关 键 词：野猪峁 特低渗油藏 启动压力梯度 注水速度
