摘　　要：A油田是我国开发较早的砂岩油田,目前油田开发进入特高含水期,面临着含水上升快,注水效益差的问题。建立油田注水及产液结构调整技术标准,定量化表征调整潜力,明确重点调整井,合理进行单砂体的强、弱水驱注水结构调整,适时进行油井堵水,可以有效控制含水上升速度,减少注入水低效无效循环,是油藏工程节能的有效手段。通过精准注水结构调整,年节约注水86.75×10^4 m^3,减少无效产液27.61×10^4 m^3,节约用电720×10^4 kWh,节约电费458.64万元,取得了好的节能效果和经济效益。A Oilfield is one of the early sandstone oilfields developed in China. At present, the oilfield development has entered the ultra-high water cut period, and it is faced with the problem of rapid rise of water cut and poor water injection benefit. Set up the technical standard oilfield water injection and production structure adjustment, the quantitative characterization of adjustment potential, clear focus adjustment Wells, the reasonable single sand body, the strong and the weak water flooding of water injection structure adjustment timely to oil well water plugging, can effectively control water cut increase speed, reduce the injection water inefficient invalid loop,is an effective method for reservoir engineering and energy saving. Through precise water injection structure adjustment, the annual water injection is saved at 86.75 × 10~4 m^3, the invalid liquid is reduced at 27.61 × 10~4 m^3, the electricity is saved at 720 × 10~4 kWh, and the electricity cost is saved at 4 586 400 yuan, achieving good energy saving effect and economic benefit.
